All-
As we know, one of the biggest bugs in Outlook for Mac 2016 is the ever-so-annoying repeated password prompt problem. This refers to the constant pop-ups that make it appear like Outlook is forgetting your password every few minutes, etc. The problem was much discussed during the Preview phase of Office for Mac 2016 but never corrected. I did some digging on the forums here and found other threads that covered this problem with slight variances, but the core issue is the same -- credentials are somehow not being stored properly or become corrupted during normal operation of the software. List of the relevant threads I found below. This list may not be comprehensive:
It seems odd that a major bug like this remained unresolved after the official release of Office for Mac 2016 ... and still hasn't been corrected! Per post responses on Microsoft's official Office Blog, they are looking into authentication issues with Exchange Server, but who knows what that means or how long that will take. Based on what I can gather:
e.g. username@DOMAIN vs. DOMAIN\username vs. username
A ticket submitted by forum member *Filip Herman* to Microsoft's technical support around early August 2015 indicated that Microsoft is aware of the problem and has a planned fix in progress. Obviously its been years since that. Others have submitted tickets to support since. Scroll to the end to read the most current progress.
I'd encourage everyone to mark this post, indicating that you "recommend this discussion." This thread has tens of thousands of views and hundreds of comments, so its clearly not an isolated issue. Unfortunately, my company abandoned the use of Outlook for Mac 2016 some while back because of this issue, so I don't have an active platform to test on anymore. However, keep trading ideas here as needed.
Best of luck-

Using older versions of Outlook for Mac in business environments

Thanks, Kiristine. This happened to me today for the first time, though I change my password monthly. Have been trying all the proposed solutions for the past 2 hours. Yours did the trick!
This problem remains. My password is not being recognised in setting Gmail in outlook on Outlook version 15.13.1 Quite irritating...
15.13.1 - issue is resolved for me. Also seems to have fixed a graphical glitch on calendar display (black bars) and crashing less frequently. No issues observed with sync errors or connection to Exchange
Same exact behavior here. I tried it out and thought it would be ok as it connected enough that I would receive and send email pretty quickly. But then I found it was limiting me in other functionality, like adding shared calendars as it would not let me do that due to the 'not connected' status. So I was forced to downgrade back to 15.8 for it to be fully functional :-( . It was progress, but still not acceptable for me. Fingers crossed the next update will resolve this other bug.
I am experiencing exactly the same behaviour. No resolution but at least I am getting mail and can send (eventually).
I have also also noticed that the reading pane does not update all the time. Seems to get stuck on a message for a while. Eventually it un-freezes but not sure why, maybe it is the same as the stuck send mail and it is waiting for a push from Exchange.
