Outlook for Mac 2016 - Repeated password prompts still an issue ...

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:

  • Bug shows up in Outlook for Mac versions 15.9.x and up, therefore ...
  • Version 15.8 and earlier are not affected, but that is a super old preview version from 2015
  • Changing the way you present your credentials can sometimes help:

            e.g. username@DOMAIN vs. DOMAIN\username vs. username

  • Problems seem to affect Exchange Server authentication as well as IMAP or POP,
  • Deleting your account and setting up Outlook from scratch sometimes helps,
  • The issue seems to be intermittent, comes and goes.

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-

    This totally worked for me. I have been following this topic for a long time now and tried everything along the way. Deleting the entries in keychain, changing the username configuration, everything. Nothing worked completely. Some things succeeded in making it take longer between password requests. But it still prompted me. 

    Then I removed the account, restarted Outlook and re-added the account as an Outlook.com instead of Exchange. That was four days ago and it's been perfect since (knocking on wood, crossing fingers). ;-)

    Thanks everyone for all your replies.

    Good luck all.

    I am using 15.24 (160707)

    The password function finaly worked after several hours. Seems unstable. Password worked fine on the web-login, but the outlook client seems like a bad thing.

    In about May of 2016, the repeated password prompt began and has not stopped since.  When I check my account under preferences, the password is gone. I re-enter it. The next time I am prompted for my password, it is gone again.  Everything was working fine before May, then one day to the next, this problem.

    In addition I keep getting the same reminders (often for past events) reappearing throughout the day.  I wonder is this issue is linked to the password issue.
