Good morning everyone,
Over the past several months we've been experencing a very random issue where Outlook loses users credentials, and then when loading Outlook it prompts for the password, but goes away so quickly you don't have a chance to enter the password.
Steps we have taken to resolve the issues.
1. We've cleared credential manager on the system
2. Repaired office (both quick and online).
3. Created new Outlook profiles (including deleting the .ost file).
4. Uninstalled/reinstalled Office completely.
Most times it works itself out after a few days, but I don't get why this issue continues to happen.
Any helpful tips?
thanks in advance

Thanks all for the hints. Recently I have run into this issue on O365 locally installed, after going back in System Restore due to mouse driver failure after update (random duplications and clicks). After restarting, Outlook displayed the "Need Password" request at the bottom, but the Password window just disappears in a matter of milliseconds ( I hardly see sometimes a part of window frame being drawn, before it's gone).
Ridiculously, I tried in a sequence all of the above, and still no luck.
The last thing, I will probably try, is to uninstall completely O365 and try to install normal Office 2019 (not 365), unless somebody has another tip what to try...

This issue started for me after I enabled "App protection policy" in intune. I went back and excluded my laptop from the App Policy and Outlook started working. I will investigate later and see why app policy caused this issue.

This post gave me some hints into solving my issue, thanks all.
I'm using Windows Virtual Desktop (WVD) with Windows 10 20H2 Multi-Session with FSLogix, and users are MFA enabled. Only after a few days of using the desktop, they have the issue where Outlook or Teams cannot open anymore and when we try to reconfigure outlook it doesn't find the account at all.
Simply disabling MFA solves the issue, but that's not an option. On Multi-Session, it's not possible to Hybrid Join so it might be another factor affecting the SSO mechanism of WAM...
Hope it'll help others as I spent 2 weeks on this.
