ISSUE
You are prompted to sign into Outlook for your Outlook.com account and receive the error dialog below.
Or, you already have your Outlook.com account added in the Outlook Profile, but "Need Password" is displayed on the Status Bar. When you attempt to sign in with your Outlook.com account you receive the error dialog below.
"You can't sign in here with a personal account. Use your work or school account instead."
STATUS: WORKAROUND
The Outlook Team is investigating this issue for a fix.
To work around the issue, you can turn off Support Diagnostics, which turns off the option to submit an In App ticket using Help and then selecting Contact Support. The bug is related to how Outlook is authenticating for the diagnostics in some situations.
To turn off Contact Support set the policy in this article and below, Disable support diagnostics in Outlook.
Code:[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Options\General] "DisableSupportDiagnostics"=dword:00000001
This is how the registry key will appear in Registry Editor after you set it.
Note: Consider adding a reminder to your Outlook calendar for late December to check back to this article for the fix status and remember to remove the policy registry key so you can continue using Contact Support. You can also temporarily turn off the workaround if you need to submit an issue in the interim.
