Getting certificate error in Outlook

We have an onprem Exchange server (2013) and Ouitlook 2010/2013 users.  

I have one user out of 500 getting a certificate error every time she launches outlook.  It's only this one user.  She's connecting to one of our CAS servers and getting the message that the cert doesn't match.  Of course, she can click ok and it works fine, but she gets the prompt every time.  

Any ideas on how to clear this?  I mean I could remove her profile and add it back, but that seems extreme.

Thanks

Cliff

It could be because of multiple reasons, the best thing to get the root association to the problem is to check detailed the error message.

Additionally of telling that the name does not match, for example, when you open the details you are suppose to see the name that you are trying to invoke vs the names included in your certificate (You can get all of these details digging the error window from the client user).

Here some general basic things to review:
- If that user has set a proxy server for Internet Explorer, ensure that the necessary exclusions are included in the settings.
- If possible, try configuring that user in a different computer (to discard that it is related to any user setting).
- If possible, try a different account on the same computer (to discard that it is a problem with the computer itself).
- Validate that the user's computer is not using special settings, such as uncommon entries in the hosts file or registry configuration files applied in the Windows registry for Office.
