    Microsoft working on a fix as soon as tehy can!

    In the meanwhile I have a workaround which should help you.

    1. Go to KeyChain Access

    2. Search "Exchange" under Login --> All Items and delete everything

    3. Search "Office" and delete everything

    4. Search "ADAL" and delete everything

    5. Launch Outlook

    6. You will get the activation prompt and then If account is already added you will see the password prompt for app and ADAL again.

    Please do 2-Factor Authentication if asked to and you should be able to login. After this on each launch you will not face the issue temporarily.

    This is not a permanent fix but will help for a little bit.

We are starting to see this a lot since the return of everyone from holiday.

I have well over 800 users using outlook for mac 2016. 

Deleting the keychain entries mentioned resolves the issue but the call volume for the problem is increasing.

Is anyone aware of what changed to cause the issue? 

Window server 2012 r2 ADFS

    It just started for me the past several days, where I could not login to Outlook (mac client) at all. It had never happened before. I am not sure what caused it .
