Supported email service configurations for server-side synchronization
Applies To: Dynamics 365 (online), Dynamics 365 (on-premises), Dynamics CRM 2016, Dynamics CRM Online
Note
The information provided here is for versions of Dynamics 365 prior to Dynamics 365 (online), version 9.0. For the latest documentation, see Supported email service configurations for server-side synchronization.
Depending on your Microsoft Dynamics 365 installation, you may be deciding whether to use server-side synchronization or the Email Router/Outlook synchronization. This following table lists what is supported by server-side synchronization for each type of installation. Later in this topic, you can read about the scenarios that aren’t supported by server-side synchronization.
Important
-
The information here includes the POP3/SMTP systems supported by Microsoft. Although other POP3/SMTP systems might work with Dynamics 365 (on-premises), those systems were not tested by Microsoft and are not supported.
-
Outlook on the web is not supported in a hybrid deployment: Dynamics 365 (on-premises) with Exchange Online.
-
You can create two different email server profiles: one for online mailboxes, and another for on-premises mailboxes. Associate the mailboxes with the correct email server profile.
-
Manual tracking in Dynamics 365 for Outlook is not supported when a user’s mailbox is configured to use server-side synchronization with the POP/SMTP protocol.
-
For Microsoft Dynamics CRM Online 2016 Update 1 and December 2016 update for Microsoft Dynamics 365 (online), we support service encryption with Customer Key in Exchange Online with server-side sync.

Using Exchange Online with Dynamics 365 (online)
If your company is using Exchange Online with Dynamics 365 (online), note the following:
Dynamics 365 (online) supports server-side synchronization with Exchange Online in the same tenant in Office 365 with Server to Server Authentication. Other authentication methods or settings are not recommended or supported, including:
Using credentials specified by a user or queue
Using credentials specified in an email server profile
Using Impersonation
Setting Auto Discover Server Location to No
Using an email server profile other than Microsoft Exchange Online
Using non-default network ports
Connecting Dynamics 365 (online) with Exchange Online in different tenant is not supported.
Unsupported email service configurations
Server-side synchronization doesn’t support the following scenarios:
Mix of Exchange/SMTP and POP3/Exchange
Creation of mass email marketing campaigns
Extensibility scenarios like extending EWS/POP3/SMTP protocols and creating custom email providers
Exchange Server 2003 and Exchange Server 2007
Server-side synchronization in Dynamics 365 (online), or in a Microsoft Dynamics 365 (on premises) deployment that is configured for FIPS 140-2 compliancy, requires a POP3/SMTP email server that is also FIPS 140-2 compliant. Some email servers are not FIPS 140-2 compliant, such as MSN, Outlook.com, or Windows Live Mail.
Multi-factor authentication isn’t supported for Dynamics 365 (online) to Exchange Server (on-premises), and Dynamics 365 (on-premises) to Exchange Online.
For most situations not supported by server-side synchronization, you can use the Microsoft Dynamics CRM Email Router. More information: Integrate (synchronize) your email system with Microsoft Dynamics 365
Note
We recommend that you don’t use a mixed configuration of Outlook synchronization and server-side synchronization for appointments, contacts, and tasks in the same organization, because it may result in updated Dynamics 365 data not synchronizing to all attendees.
