Password required Office 365
I have seen similar behavior in our organization as well.
Try using - HKEY_CURRENT_USER\Software\Microsoft\Office\x.0\Outlook\AutoDiscover registry key...

If that did not work user SARA - Support and recovery assistant from MS. You can download it from the below link -

SARA is an MS tool that is used to fix a lot of Outlook issues automatically - the issue that you are facing can be fixed using SARA.
Once you install it you just have to choose the issue that you are facing from a bunch of options...
Moreover I would also suggest to delete Cached credentials from Credentials manager as sometimes old-expired cached credentials also cause this issue.
Once the credentials are cleared use the registry key that VasilMichev has recommended.
Refer the below article for more details on the Registry that Vasil has provided...

I would recommend try running SARA as it will give you the exact cause incase it is not able to fix the issue.
Here are the steps already done: - Removed all Office 365 credentials in "Credential Manager" on Windows 10 - Remove the Outlook profile from "Control Panel" and recreate a profile with a different name - Uninstall Office 365 completely and then reinstall
Another option is to (at least temporary) disable WAM:
[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Identity] "DisableADALatopWAMOverride"=dword:00000001
