Hi,

 

We are getting an error with one mail user on Outlook 2016. (See attached picture) Their account works fine in OWA It's just the client side. I have tested their account using the Microsoft remote connectivity analyzer and their account passes the tests. I was expecting their to be an issue with IMAP but it passed that test.

 

Any ideas on what the cause could be?

 

Kind regards.

There's an ongoing issue on O365 side, which is probably what causes this:

@HotCakeX 

Thank you for your reply. There is no issue logging in to Office 365, it's when this user is logged in to a domain computer and opening up the local outlook 2016 application. 

 

Kind regards.
