Since May 2012, Microsoft has been transitioning Exchange Hosted Archive (EHA) customers to Office 365. All customers are being scheduled, notified of their transition dates, and encouraged to learn about the new service. The duration of time required to migrate messages from EHA to O365 for each transition is dependent on the size of your archive. All customer transitions will be completed by November 2013. This page provides all existing Exchange Hosted Archive (EHA) customers with information they need to transition their data from EHA to Office 365’s Exchange Online archiving.
To learn the basics about Office 365 archiving, licensing and support start by reading the following transition process primer.
Office 365 is the suite of Microsoft business productivity applications that are run as a cloud subscription service in Microsoft's data centers. For a comprehensive description of Office 365 visit the What is Office 365 page. Email archiving in Office 365 is available as part of Microsoft Exchange Online service based on Exchange 2010. Users may use the same Outlook clients - Microsoft's Outlook Web App (OWA) or Outlook 2007 and Outlook 2010 desktop clients - to access messages, contacts, appointments and tasks stored in your Exchange Online archive
As part of Microsoft's efforts to provide customers with the latest services, we have started to transition customers to Office 365 Exchange Online and will continue to move customers over the next several months. We encourage all existing EHA administrators to learn about changes to the archiving service by reading the information below which provides a high level description of things you should know, with links to expanded information.
Office 365 natively archives not only e-mail and Lync IM messages, but also Outlook Calendar, Tasks, and Contacts.
The EHA service acted as a domain catch-all for many customers. This means in many cases all messages for your domain(s) were captured and stored within EHA, even for users not provisioned within the FOPE/EHA Admin Center. These messages were collected and attributed to what we refer to as "Un-provisioned Users". With Office 365 only the messages for provisioned users will be migrated. If you need to have the messages moved for recipients that were not provisioned in EHA you will need to provision them in the FOPE/EHA Admin Center prior to the start of your transition. For greater detail on this subject visit the Un-provisioned Users page.
On-Premises customers that rely on the FOPE/EHA Directory Sync Tool (FOPE DST) to automatically synchronize Active Directory user accounts to the FOPE/EHA service should not use the Microsoft Online Service Directory Synchronization tool for user management of their Office 365 users after their EHA Transition. For more information visit the MSO DST should not be used by customers transitioned from EHA that use Journaling page.
It is important to understand the functional differences between Office 365 and EHA message Retention, Legal Hold and Litigation Hold. For example Retention Period in EHA most closely compares to Litigation Hold in Office 365. Configuring Retention is discussed in greater detail on the Litigation Hold page.
Office 365 does not natively offer Supervisory Review features. However through the use of PowerShell there are methods for manual or automatic harvesting using Search Folders to collect messages for review. For greater detail on this subject visit the Supervisory Review page.
EHA has several built-in reports but offered no ability to customize or schedule these reports. Office 365 has a smaller set of built-in reports, but through the use of PowerShell you now have the ability to customize and schedule custom reports. For greater detail on this subject please visit the Reports page.
In EHA searching your entire company is possible from the EHA Viewer client. In Office 365 the Multi-Mailbox-Search interface is limited to 5000 mailboxes at one time using the administrative Microsoft Online Portal. For searches on more than 5,000 mailboxes PowerShell can be used to search across the entire organization. For greater detail on this subject please visit the Discovery and Search page.
In Office 365 the export features of Outlook 2007 or 2010 can be used to export messages to PST files onto your local computer. For greater detail on this subject please visit the Exporting Data page.
In Office 365 you can import historical data that is in PST format using the free PST Capture tool. For more information about the PST Capture tool visit the Microsoft Exchange PST Capture tool page on Technet. To download the tool please visit the Microsoft Exchange PST Capture tool download page.
Office 365 does not support Bloomberg messaging and only supports Microsoft Lync Instant Messaging. Because of this Bloomberg and Instant Messaging data in EHA will not be migrated to Office 365. For Bloomberg and Instant Messages there is 3rd party software that may support ingesting this data into Office 365.
Office 365 has a message size limit of 25MB and messages in EHA that exceed this limit will not migrate. This message size limit will also impact the ingestion of future messages which are sent to Office 365 through Journaling.
Un-migrated messages will be returned to you on encrypted media. For greater detail on this subject please visit the EHA Data That Will Not Migrate to Office 365 page.
A new Letter of Attestation (LOA) has been created for Office 365. If you have an EHA LOA it is important to understand that it does not apply to Office 365. If you have requested an LOA previously for EHA and need an LOA for Office 365, you may open a support request with Office 365 Support by following the instructions on the Contact Support for technical issues page.
There are three e-mail environment scenarios that affect your transition to Office 365. Please read the descriptions that follow then return to the top of this page and choose the scenario tile that corresponds to your current e-mail environment. Selecting your scenario provides you with environment specific information on how to get ready and what to expect before, during and post transition.
If you have any questions please contact EHA Technical Support using Get Help Now by logging on to the FOPE/EHA Admin Center or by calling 1-866-291-7726.
EHA transition for customers who have an on-premises Exchange server
The following information describes things you should know and what to expect if you run your own Microsoft Exchange e-mail server and do not have any mailboxes hosted in Microsoft Office 365 Exchange Online service.
This information describes actions you should take before your transition begins.
Microsoft will send a notice approximately thirty days in advance of the beginning of your scheduled Exchange Hosted Archive (EHA) transition to Office 365's archive. Please identify one person at your company that will act as the Transition Contact and update their FOPE/EHA Admin Center contact to include an SMS text enabled cell phone; as well as an out-of-band e-mail address (example: @hotmail.com, @yahoo.com, @gmail.com, etc.); and finally add the words Transition Contact in the Title field. To do this log in to the FOPE/EHA Admin Center and navigate to the Administration tab, Company sub-tab, then click Add to create a new contact, or Edit to update an existing contact. This Transition Contact will be the person that Microsoft will primarily communicate with during the EHA to Office 365 transition.
If there is no Transition Contact defined, all Compliance Managers and Company Contacts listed in the FOPE/EHA Admin Center will receive notifications about your EHA Transition.
Only provisioned users, meaning those listed in the FOPE/EHA Admin Center, will have their messages migrated. You have an opportunity to provision users before the transition. For more information visit the Un-provisioned Users page. For more information about all messaging data that will not be migrated please visit EHA Data That Will Not Migrate to the Office 365 Archive.
This applies only to Microsoft Exchange Server 2003. This does not apply to Exchange Server 2007 and 2010 because those versions use Envelope Journaling natively. The journaling functionality that receives messages for archiving into Office 365 requires that the messages be in envelope journal format (in Exchange 2003 and earlier there were three types of journaling, Standard, BCC and Envelope - Office 365 cannot properly process Standard or BCC journaling formats). Typically EHA customers will have configured Envelope Journaling when first subscribing to the EHA service, however it was not a requirement for EHA. You should verify that Envelope Journaling is indeed configured. For detailed information on how journaling is configured on Exchange 2003, visit the Exchange Server Journaling to Office 365 for Transitioning EHA Customers page.
Note: Journaling to Office 365 is only offered to customers that have transitioned from EHA to Office 365.
Consider signing up for a free 30 day trial of Office 365 by visiting the Try Office 365 for free for 30 days. Be sure to select Plan E3 which includes the Office 365 archive feature. CAUTION: When creating a trial tenant, do NOT use your existing EHA or FOPE e-mail domain. This will interfere with your current Microsoft filtering services. A recommendation for creating a trial is to decorate your domain with the word ‘trial'. For example if your domain is contoso.com then use contoso-trial.com.
Sign up for EHA Transition training. The EHA Support team offers live training sessions. To attend please RSVP by e-mail to ehasup@microsoft.com, choosing one of the following weekly sessions.
Note: Sessions with no confirmed RSVP's are cancelled.
There are several steps that must be completed by Microsoft before your EHA archive data can be transitioned to Office 365. This includes creating users, assigning licenses, and establishing litigation hold with, and without, duration. Below you will find a list of actions that will be performed on your behalf.
The following information describes actions Microsoft performs during your EHA to Office 365 transition.
A few days before your transition completes Microsoft will place the EHA Admin Center into a read only state called Maintenance-Mode. From this point forward, no changes to the configuration of EHA will be possible in the Admin Center. During this time Microsoft will transition your EHA configuration and user accounts to Office 365. The EHA Viewer and Reports will still be available as normal during Maintenance-Mode. A ten day notification will be sent to your company contacts telling them when Maintenance-Mode is to begin. For more information visit the EHA Maintenance-Mode page.
After Office 365 has been configured and EHA users have been created in Office 365, Microsoft will next move EHA messaging data. The EHA Viewer and EHA Reports services also remain available while messages are migrated.
During the transition Microsoft will configure Litigation Hold with Duration on each transitioned Office 365 mailbox based on the retention period set in EHA. For example if all of your EHA users were configured to retain messages for 2555 days, then each Office 365 mailbox will have Litigation Hold with a duration of 2555 days configured. If an EHA users has legal hold enabled then the Office 365 mailbox will have Litigation Hold without a duration set, meaning save permanently until litigation hold is turned off.
Note: Office 365 retention policies are used to control and reduce the size of a mailbox. In contrast Office 365 litigation hold prevents deletion and is most similar to EHA's retention period. Please read the information found on the Message Retention and Legal/Litigation Hold page for more information.
When done you will receive a notice telling you that your transition to Office 365 has completed. Transition complete is the point in time where all messages and account data has been transitioned to Office 365 and you will stop using EHA and begin using your Office 365 archive. At this time messages are no longer being ingested in to EHA and are ingesting into the Office 365 archive. All users should immediately begin using Office 365. You can still logon to EHA, however any activity in the EHA Viewer, the EHA Admin Center or EHA Reports is for historical viewing purposes only. For approximately fifteen days you will continue to have access to EHA before it is permanently deleted.
When your transition is complete Microsoft will notify your company Transition Contact to use the Forgot your password? link, found on the Office 365 Login Portal, to reset their logon credentials to Office 365. When resetting the login password, automated answer-back e-mail and SMS messages will be sent with secure links that you will use to reset your Office 365 password.
This information describes actions you should take after the completion of your transition.
After transition add a new primary SMTP address to the journaling contact that is configured to forward mail to your Microsoft archive. For information to accomplish this visit the Update your journaling address after your EHA to Office 365 transition completes page.
After transition add a new primary SMTP address to the journaling contact that is configured to forward mail to your Microsoft archive. For information to accomplish this visit the Update your journaling address after your EHA to Office 365 transition completes page.
After transition begins you should log on to the EHA Reports page and export reports that you want to retain for posterity when there is no further access to EHA . For example the Privileged Roles reports are useful for configuring Office 365 with similar administrative permissions that existed in EHA. If you used the supervisor/subordinate review functionality you may wish to export historical Supervisory Review Evidentiary and Message Review Recap reports. To see a description of all the available EHA reports visit the EHA Reports Description page.
In addition Microsoft will include EHA specific configuration information from the FOPE/EHA Admin Center on the USB media that is returned to you with your EHA data. These will be CSV spreadsheets and will include the following information about the configuration of your EHA service:
EHA Administrative permissions and Archive Roles do not transition from EHA to Office 365. The Privileged Roles report, which shows the archive roles assigned to each EHA account; and the Employee Roster report, which shows supervisory relationships between EHA users; can be used to configure similar permissions and groups in Office 365.
If you have not been transitioned from EHA to Office 365 and you are currently planning to move your on-premise mailboxes to Office 365 in the next 90 days, please call EHA support and Microsoft will postpone your EHA migration so you can first move to Office 365, then have EHA transitioned thereafter. EHA support can be contacted by calling 1-866-291-7726.
Some types of messaging data cannot be migrated from EHA to Office 365. For more information visit the EHA Data That Will Not Migrate to Office 365 page. A full complimentary copy of your EHA will be encrypted to USB media and sent to the Transition Contact that you listed in the FOPE/EHA Admin Center.
EHA transition for Office 365 customers that are in a hybrid scenario
Companies that are using a hybrid scenario for Office 365 are not yet eligible to have their Exchange Hosted Archive (EHA) migrated to Office 365.
A hybrid deployment is one where your company has mailboxes located both on your on-premise Exchange mail servers and also on Microsoft's Office 365 Exchange Online service. Transitions for hybrid customers will be completed at the end of the EHA transition schedule. For an expanded definition of hybrid see the Hybrid deployments section on the Office 365 for IT pros web page. If you are a hybrid configuration and are sent a transition notification, please reply to your transition announcement, or call EHA Support at 1-866-291-7726, and your transition will be postponed.
EHA transition for existing Office 365 Exchange Online customers
The following information describes things you should know and what to expect if you have an existing fully hosted Office 365 Exchange Online tenant. Fully hosted means you host all mailboxes within Exchange Online.
This information describes actions you should take before your transition begins.
Microsoft will send a notice approximately thirty days in advance of the beginning of your scheduled transition. Please identify one person at your company that will act as the Transition Contact. This Transition Contact will be the person that Microsoft will primarily communicate with. To indicate this person you can add the words Transition Contact in the Title field of an existing or new contact. To do this log in to the FOPE/EHA Admin Center and navigate to the Administration tab, Company sub-tab, then click Add to create a new contact, or Edit to update an existing contact.
If there is no Transition Contact defined, all Compliance Managers and Company Contacts listed in the FOPE/EHA Admin Center will receive notifications about your EHA Transition.
Only provisioned users, meaning those listed in the FOPE/EHA Admin Center, will have their messages migrated. You have an opportunity to provision users before the transition. For more information visit the Un-provisioned Users page. For more information about all messaging data that will not be migrated please visit EHA Data That Will Not Migrate to the Office 365 Archive.
Sign up for EHA Transition training. The EHA Support team offers live training sessions. To attend please RSVP by e-mail to ehasup@microsoft.com, choosing one of the following weekly sessions.
Note: Sessions with no confirmed RSVP's are cancelled.
There are several steps that must be completed before the archive data can be transitioned from EHA. This includes creating users, assigning licenses, and establishing litigation hold with and without duration. Below you will find a list of actions that will be performed on your behalf.
Note: Only Office 365 users that were also EHA users will have mail data migrated from EHA and will have their Office 365 Litigation Hold settings modified to match EHA's retention period and legal hold settings.
This information describes user experience you should be aware of and actions you should consider during the transition.
If users already have Office 365 archive folders, then nothing will change in their folder list. Users who do not have Office 365 archive folders will have archive folders enabled during the transition. While messages are copying from EHA to Office 365 all users will see migrated messages appearing in their archive folder's inbox. Note that if no data is migrated from EHA to an Office 365 mailbox, then no archive folders are created, and the Office 365 mailbox is untouched by the transition.
Note that users may see duplicate messages in their Office 365 archive folders. Messages that are migrated from EHA to Office 365 are placed in the archive mailbox folders. These messages are not inserted into the user's primary inbox. Also, as archive retention policies automatically move, and users manually move, messages to their archive folders these will become duplicates of the messages copied from EHA. This is expected and normal behavior and will persist until these transition-era messages are deleted based on your long term retention and litigation hold settings.
There may be EHA users that exist only in EHA and do not exist in your Office 365 user list, for example EHA users that are no longer employed at your company. These EHA users will be created in Office 365 and their EHA data will be migrated. These transitioned users will appear in your company Address Book (Global Address List/GAL). After the transition if you prefer that these new users not be shown in the GAL you can use PowerShell to hide them using the instructions how to Hide a User from the Shared Address Book in Office 365.
You should review your Office 365 retention policies to make sure they are configured as desired. For example if you were transitioned from Microsoft BPOS to Office 365 a default delete policy after one year was applied to your transitioned mailboxes. Now that your Exchange Online mailboxes have Archive folders it is recommended that your retention policies be updated to move messages to the Archive folders rather than delete them.
During the transition Microsoft will configure Litigation Hold with Duration on each Office 365 mailbox based on the retention period set in EHA. For example if all of your EHA users were configured to retain messages for 2555 days, then each Office 365 mailbox will have Litigation Hold with a duration of 2555 days configured. If an EHA users has legal hold enabled then the Office 365 mailbox will have Litigation Hold without a duration set, meaning save permanently until litigation hold is turned off.
Note: Office 365 retention policies are used to control and reduce the size of a mailbox. In contrast Office 365 litigation hold prevents deletion and is most similar to EHA's retention period. Please read the information found on the Message Retention and Legal/Litigation Hold page for more information.
The following information describes actions Microsoft performs during your transition.
Approximately ten days before your transition begins Microsoft will notify you that the EHA Archive will soon be placed into a read only state. From this time forward no further changes to the configuration of EHA will be possible and all changes relevant to archiving should be made in Office 365.
Microsoft will disable the EHA journal rule in Office 365 that sends mail to the EHA copy address (journaling rules are located in the Office 365 Microsoft Online Portal under the Exchange section, under Manage, Mail Control, Journaling). From this point in time new e-mail will be ingested in Office 365 only and will no longer be ingested into EHA
Microsoft will next move EHA messaging data over the next several days and users will notice this data arriving in their Office 365 archive folders. The EHA Viewer, as well as the FOPE/EHA Admin Center and EHA Reports services will remain available until approximately fifteen days after you are notified that the transition is complete.
You will receive a notice informing you when your transition has completed. For approximately fifteen days you will continue to have access to EHA before it is permanently deleted.
This information describes actions you should take after the completion of your transition.
After transition begins you should log on to the EHA Reports page and export reports that you want to retain for posterity when there is no further access to EHA . For example the Privileged Roles reports are useful for configuring Office 365 with similar administrative permissions that existed in EHA. If you used the supervisor/subordinate review functionality you may wish to export historical Supervisory Review Evidentiary and Message Review Recap reports.
