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-

    I have exactly the same issue with versions up to and including 15.11. It's really dissapointing that no one from MS is taking this up to get a concrete resolution.........

    Thank you for your suggestion.  I tried this procedure a while back because it seem to work for so many  people; however, it did not work for me.  😟

    I've been having the same problem with the last 3 releases of Outlook 2015 and I have tried every trick in the book to no avail. Outlook keeps pestering me for my Exchange Password. 

    Interestingly whatever I do, the password field in the preferences/account panel is regularly being wiped out...

    Clearly this bug is resilient...

    Hi All,

    I had this issue as well. With 2011 AND 2016 office. I solved it by disabling the auto-discover. Please see this page for details. Hope it helps as well.

    This script will give an error, but it will work anyway. 

    https://stackengineer.com/macos/disable-exchange-autodiscover-outlook.html

    Disable Exchange Autodiscover on Outlook<br><br><br><br><br><br>While Autodiscover with Microsoft Exchange can be great, sometimes a company can have a rather difficult DNS setup. Maybe it's their use of internal and external DNS servers with different IP addresses and hostnames for the mail server if you're on the network<br> (in the office) versus when you're not. This can wreak havoc on Outlook's autodiscover feature. To disable Autodiscover, close Outlook completely, launch AppleScript, and type the follwing command (be sure to change AccountName to the profile name in Outlook.<br><br><br><br><br><br><br> tell application "Microsoft Outlook"<br> set background autodiscover of exchange account "AccountName" to false<br> end tell<br><br><br><br>After you hit the play button to run it, you can close AppleScript and reopen Outlook. Autodiscover will now be disabled so whatever server settings you put in, will stay.

    Well, this post is from 2015 ? God.. 

    Still today, With Outlook for Mac Version 15.36.1 I'm getting the password prompt every hour. It's very annoying. 

    I already removed the Keychain entry, re-added, re-configured my account, I took long and deep reading on Logs and looks like Outlook isn't able to correctly read the Keychain kept password.

    So far, no solution ... I keep typing my password every hour.
