Outlook Plugin unable to authenticate after SSL upgrade

Posted on by 2

I've searched a lot of answers online but haven't been able to find anything.


We recently updated the SSL wildcard cert of an on-prem Dynamics CRM. Everything is working now after the upgrade, EXCEPT the Outlook Plugin can longer authenticate. I'm not sure what might have changed.

Previously when initially setting up the CRM Plugin it would prompt for sign in with a blue-color sign in box, it looked similar to the default Dynamic Web GUI log in.

However, now it pops up with a Black-titled box, and no matter which credentials are entered it gives an error that 'authentication failed.'

I'm not sure what setting needs to be changed to get the previous pop-up box to appear, the one that actually worked.


Could anyone point me in the right direction about this issue? Thanks!

    We are experiencing the same issue.  365 on-premise.  After updating, the app fails at the AuthenticationProvider step.  We tried to re-enable the mailboxes and that didn't work.  Did you ever figure this out?
