When you sign in to Microsoft Lync Online by using Microsoft Lync 2010 or Microsoft Lync 2013 on a computer that's running Microsoft Outlook, you receive the following error message:
There was a problem connecting to Microsoft Office Outlook. The email address used in your default Outlook profile is different from the sign-in address used in Lync 2010. Change your default Outlook profile to match the sign-in address you are using in Lync, and then sign out and sign back in to Lync.
To resolve this issue, make sure that the Exchange account in Outlook matches the account that's used to sign in to Lync Online. If the Exchange mailbox and the Lync account are both hosted by Microsoft Office 365, make sure that the user’s Exchange primary Simple Mail Transfer Protocol (SMTP) address matches the user principal name (UPN).
You can use the Set-MsolUserPrincipalName
cmdlet from Windows Azure Active Directory Module for Windows PowerShell to set the UPN, SMTP, and Session Initiation Protocol (SIP) address to the same value. For more information about this cmdlet, go to the following Microsoft website:
If the Exchange mailbox is hosted elsewhere (for example, if the mailbox is hosted on an on-premises Exchange server), see the following Microsoft Knowledge base article:
How to set up Lync Online in Office 365 to interoperate with an on-premises Exchange environment
After the UPN, primary SMTP, and SIP address are configured correctly, repair or re-create the Outlook mail profile by using the new primary SMTP address, and then restart Lync.Note
When you're repairing or re-creating the Outlook mail profile, the email address that Oulook automatically detects should match the user’s SIP address. If the addresses don’t match, either the SMTP address or the SIP address is set incorrectly.
The main cause of this error is a mismatch between the accounts that are used in Outlook and Lync. The Exchange mailbox to which Outlook is connected must be associated with the same Office 365 user account to which Lync is connected. If Outlook is connected to a mailbox that's part of another Office 365 organization or another on-premises Exchange organization, you may receive this error. When Lync tries to make a connection with Outlook, it compares the SMTP (email) address in Outlook with the sign-in address that's used to connect to Lync Online. If the SMTP and Lync sign-in address don't match, you may receive this error.
This error can also occur when Lync is expecting to integrate with a different mailbox from the mailbox that's configured in Outlook. For example, if Lync expects the user’s email address to be email@example.com, but Outlook is connected to the mailbox for firstname.lastname@example.org, you may encounter this error.
Lync uses the WindowsEmailAddress or MAIL attribute to determine the Exchange server to which Outlook should connect. If Lync makes that connection through Exchange Autodiscover and Exchange Web Services (EWS), and if Outlook is configured for another user’s mailbox, Lync registers that as a problem and reports the error.
