Outlook keeps asking for password
Hi, we are having an issue with Outlook with an Office365 account on some user. the password prompt are keep on showing. I tried running SARA, update windows 10 and office apps, create new profil...
- Ok so now I tried the same registry settings on a computer with Office 2016 and IT WORKS!
Oh course I had to change for version 16 in the registry.
HKEY_CURRENT_USER\Software\Microsoft\Exchange\AlwaysUseMSOAuthForAutoDiscover REG_DWORD 1
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity\EnableADAL REG_DWORD 1
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity\Version REG_DWORD 1
Hi Jeesoo,
Make sure that modern authentication is enabled on the tenant:
Microsoft 365 admin center > Settings > Org Settings > Modern Authentication.
If the key HKCU\SOFTWARE\Microsoft\Office\15.0\Common\Identity\EnableADAL exists than the DWORD has to be set to 1 (https://learn.microsoft.com/en-us/exchange/troubleshoot/administration/modern-authentication-configuration)
If these solutions don't work, try to create a new Windows user profile.

MathieuVandenHautte life-saver! I'd found this registry entry but the page I'd found said it had to be set to 0 not 1 - doh! Not sure WHY this key hasn't made it into some of my client's computers. Caused all sorts of hassle today as basic authentication was disabled.
