Outlook Password prompt disappears quickly

Occasional Contributor

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...

@jsyrovat SOLVED, I went to Settings->Accounts->Work or School and found saved credentials, so I tried to remove it, and after that Outlook after restart prompted correctly for a password and connected to server.



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...


Here is how I solved the issue, keeping MFA:
Add the following Registry keys to disable WAM (Web Account Manager) and revert Outlook back to ADAL (Active Directory Authentication Library):
  • [HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity "DisableADALatopWAMOverride"=dword:00000001
  • [HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity "DisableAADWAM"=dword:00000001


Hope it'll help others as I spent 2 weeks on this.



Thanks@jsyrovat this solution worked for me

Należało by zapytać o pełne środowisko w którym współpracuje Outlook !
Błąd który opisano nie wynika z problemu Outlook według mnie tylko z dodatkowych czynników związanych z zabezpieczeniami lub nie właściwą konfiguracją urządzenia.
Lub nie dokończonej aktualizacji !
Umiejętność synchronizacji może też zakłócać wirus ! wtedy reakcja Outlook taka właśnie jest ponieważ następuje zakłócenie nie potwierdzone i to jest prawidłowa reakcja Outlook !
Proponuję Synchronizację konta Outlook z programem Poczta dla Windows 10
To rozwiązanie działa fantastycznie ponieważ autoryzacja i potwierdzenie konta zapewnia program Poczta dla Windows 10 i proszę mi wierzyć że nie ma problemów !
Proszę sprawdzić i jeżeli będziecie zadowoleni

To proszę o polubienia tego postu
Dziękuję bardzo

What worked for me is to go to Windows 10 Settings > Accounts > Access work or school > Disconnect the account there, then log in with Outlook and it then it worked for me. The registry settings didn't fix it for me.  @dhendrix24 

Thanks Hugo! After fighting with this for 3 hours, and trying all the other suggestions, these registry changes fixed it!
We recently switched from GoDaddy to Microsoft for our Office 365 subscriptions and had this issue trying to get all our users logged back in. Despite trying multiple registry changes, including those listed here, it was an easy fix that @ahuli12 and @jsyrovat pointed out:
