You’re seeing the following error message:

“To track emails and perform synchronization, your Outlook email address should be the same as your email address in Microsoft Dynamics 365.”

This message is common when you have multiple Office Outlook email addresses or have access to more than one Dynamics 365 organization. For example, your company may use multiple Dynamics 365 organizations for testing or upgrade purposes.

You may also see this error message if you are configuring Microsoft Dynamics 365 for Outlook, but you don’t have an Outlook email address, or you haven’t set the primary email address field in Dynamics 365.

To fix this, start by finding the primary Outlook email address:

Find the primary Outlook email address

  1. In Outlook, choose File.

  2. Under Account Information, choose Account Settings, and then select Account Settings from the list.

    In the Account Settings dialog box, you’ll see a check mark next to the primary email address. Make a note of the exact address.


    You must use the exact email address that you see in the Account Settings dialog box. For example, the following email addresses are not equivalent:
