Client Features in Exchange Online Archiving

Office 365
 

Applies to: Office 365

Topic Last Modified: 2014-05-02

Microsoft Exchange Online Archiving allows users to connect to their archive mailboxes from a variety of devices and platforms. All network connectivity to the user’s archive occurs over the Internet, and virtual private network (VPN) connections are not required. Organizations can publish an on-premises Client Access server to allow users to access their primary mailbox using Outlook Anywhere, without requiring a VPN connection. If VPN access is required to access the user’s primary mailbox located on an on-premises server, this requirement does not change.

ImportantImportant:
Microsoft reserves the right to block or throttle connections from any client software that negatively impacts the health of the Exchange Online Archiving service.

Microsoft Outlook is a rich email program that includes support for calendaring, contacts, and tasks. Exchange Online Archiving supports Outlook 2013, Outlook 2010, and Outlook 2007. Key features include:

  • Outlook Anywhere   Outlook Anywhere lets Outlook users connect to Exchange Server and Exchange Online Archiving over the Internet with no need for a VPN connection. Communication between Outlook and Exchange Online Archiving occurs via an SSL-secured tunnel, using the RPC-over-HTTP Windows networking component.

  • Autodiscover   The Exchange Autodiscover service automatically configures Outlook to work with Exchange Online Archiving. Autodiscover enables Outlook users to receive their required profile settings directly from Exchange the first time (and at fixed intervals thereafter) that they sign in with their email address and password.

Outlook 2010 and later and Outlook Web App provide users with the full features of the archive, as well as related features like retention and archive policies.

Outlook 2007 provides basic support for the archive, but not all archiving and compliance features are available in Outlook 2007. For example, with Outlook 2007, users cannot apply retention or archive policies to items in their mailboxes. They must rely on administrator-provisioned policies instead. Outlook 2007 users require the Office 2007 Cumulative Update for February 2011 to access the archive.

NoteNote:
Outlook is not provided with Exchange Online Archiving. Microsoft Office 365 ProPlus (which includes Microsoft Outlook) is included in some Office 365 plans and can be purchased as a separate subscription. For more information, see Office 365 Plan Options. For more information about Office 365 ProPlus, see the Office Applications Service Description.

Additionally, Outlook 2007 users cannot search the on-premises mailbox and the archive at the same time.

Outlook Web App is a web-based version of the Outlook email program that is used with Exchange Online. Wherever users are connected to the Internet—at home, at the office, or on the road—they can access their email through Outlook Web App.

Users can access their archive by signing in to Outlook Web App on-premises (using the same URL). The archive appears alongside their primary mailbox in Outlook Web App. There is no explicit way to access the archive directly from Outlook Web App.
