Microsoft is working on a fix for ongoing sign-in issues affecting some Outlook for Microsoft 365 customers and preventing them from accessing their accounts.
The login problems impact users trying to sign in to Outlook using their Outlook.com accounts or those who have already added the accounts to their Outlook profiles.
Instead of logging in, the users will see the following error messages asking them to use a work or school account: "You can't sign in here with a personal account. Use your work or school account instead."
While Microsoft says that the Outlook Team is working on a solution for this known issue, an official workaround is available for those who want to access their accounts until a fix rolls out.
"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," Microsoft said.
To disable support diagnostics in Outlook and prevent it from communicating client information on failure to support services, you have to enable the DisableSupportDiagnostics policy setting.
