- HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity, create a DWORD value named EnableADAL and set it to zero.
- Under the same registry key, create a DWORD value named DisableADALatopWAMOverride and set it to 1
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.
