Outlook 2016 - User Mismatch with Skype RRS feed

  • Question

  • We have a unique scenario where our Primary SMTP needs to be different from our Primary SIP.

    However this results in Outlook 2016 refusing to create a Skype Meeting and fails with a "User Mismatch" error because SMTP & SIP do not match.

    Skype server has a policy to disregard this mismatch. Does Outlook? Is anyone aware of such a workaround?

    Cheers,

    Matt

  • What Exchange are you running? On-Prem or O365? Ensure the OAB is pointed at O365 and not on-premises if you're in Exchange hybrid.

    Thanks for visiting our forum. Then sorry that here we mainly focus on general issues about Outlook desktop client, since your query is related to the Sky for Business integration. I'll move your thread to the Skype for Business forum for more dedicated response. 

    The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.

  • Hi Matt,

    Agree with ngarver586, you could refer to the blog to troubleshooting the issue:
    1. In the SFB Server side, make sure the value of DisableEmailComparisonCheck is True in the client policy you assigned to the user.
    2. In the Outlook client, make sure the user’s email account is set as default account. 
    3. Try to delete the following files in the PC:
    drive:\Users\<username>\AppData\Local\Microsoft\Outlook
    drive:\Documents and Settings\user\Local Settings\Application Data\Microsoft\Outlook

    Best Regards,
    Evan Jiang
