Microsoft Rolls Out Security Fixes Office For Mac
If you are an Office preview member on Mac, you are getting a new update for the Insider Program. Microsoft has rolled out the latest release for its productivity suite on Apple’s platform.
Since last week, a lot of our users are bothered by Outlook 2016's credentials prompt. Entering credentials just makes the prompt show again, only canceling it and clicking the 'needs password' text in the bottom of Outlook's main window allows them to keep working for a while. So far 15 out of our 42 active Windows Outlook users have been impacted (not counting Mac Outlook, or holiday users).
Everyone is using Outlook 2016 on Windows 10, Office 365 (hybrid setup with all user boxes in the cloud). Yesterday I've had everyone delete their stored Windows 10 credentials. This looked like it solved it for a few hours, but today impacted users report the same behaviour.
All are on the same hardware, so it's very odd that not everyone is impacted. There was no relevant change on our part afaik. I'm assuming this was an update of software/OS. Following other cases has not lead me far, I can't choose auth method (basic/ntlm) in 2016+365 Any leads to the cause are welcome. I've logged a MS case, with not much feedback so far. The issue for me was WAM. Solution: HKEYCURRENTUSER Software Microsoft Office 16.0 Common Identity 'DisableADALatopWAMOverride'=dword:00000001 Reply from Microsoft: By default, Microsoft Office 365 ProPlus (2016 version) uses Azure Active Directory Authentication Library (ADAL) framework-based authentication.
Starting in build 16.0.7967, Office uses Web Account Manager (WAM) for sign-in workflows on Windows builds later than 15000 (Windows Version 1703, build 15063.138). Workaround: HKEYCURRENTUSER Software Microsoft Office 16.0 Common Identity 'DisableADALatopWAMOverride'=dword:00000001 The regkey disables WAM use in Office, which can degrade the auth experience (users will see legacy UI and may be prompted more in other cases, so it's only recommended if the situation is blocking).
We highly recommend deleting the regkey once the fix is out. The fix for Windows 10 should be shipped early next year, I%u2019m now trying to check ETA. We've been having this problem since Friday 7/28 around 2pm with about 60 of our users. We finally got Microsoft to admit there is a problem and are now waiting on a resolution. Even though they say our tenant is no affected by it, but it obviously is. This is also not showing up on the health report.
This was the last response we got from them yesterday on the issue: Thank you for your time on call. As discussed over the call, I'm summarizing the discussion here: We had several tenants reporting the same password prompts issue in Outlook client.
We took the required logs from all the tenant and involved our backend team into this ongoing issue. As per the update received from the backend team, the issue seems to emerging and the associated SI seems to be: EX111618 The issue is supposed to be resolved once the SI gets fixed.
The backend team is still working on this issue and once we receive any updates from them we would let you know. It would be recommended to keep a check on the emerging issue: EX111618 from the portal. Your patience is much appreciated and thank you for contacting Microsoft Partner Cloud Support. Have a nice day ahead.

I have Office Professional 2016 (version 1708) on Win 10 laptop. Issue has been happening since last Thursday September 28. Issue progressively got worse. At first accepting my credentials, then not at all. Pop-up keeps appearing.
Outlook will not connect to the Exchange server. I have wiped out Credentials - does not work I removed.ost file. Worked for a short time on Friday. Now, this morning. Broken again. The pup-up asking for password keeps appearing and won't accept password. Is there a true fix for this?
The issue most certainly is NOT resolved. Happened to me countless times in the past hour. Has been on on-going issue for me ever since I installed Outlook 2016 on my Windows 10 laptop over a year ago now. As I have several different email accounts, I have Outlook configured to poll all accounts for new mail every minute.

Sometimes I think this issue has gone away as I may not be prompted for password sometimes for several weeks. But sooner or later it always starts back with a vengeance and is going berserk today! Renders Outlook basically useless when this is happening unless you don't mind dealing with the multiple account password prompts every one minute! I'm a private user, not on an exchange server.
