Modern auth needs to be enabled client-side as well, in the case of Office 2013 you need to be running at least SP1 if you're on the MSI version. Check the reg keys, check for any GPOs that might be blocking this. Make sure to remove any stored credentials from cred manager, and also try with creating a new Outlook profile.

Did you check the reg keys (as detailed for example here: https://docs.microsoft.com/en-us/microsoft-365/enterprise/modern-auth-for-office-2013-and-2016?view=o365-worldwide) and the matching keys under Policies subtree (GPOs)? Your mailboxes are all in Exchange Online, right?

Hi Michev

I have follow this document above already.

  1. I have check on exchange 365 to make sure the exchange servver side have modern authentication turned on.

  2. add the registry keys in for the end device to make sure outlook 365 use modern authentication.

Yes my mailbox is in exchange online.

Is there a possibility to test from a different device, just to exclude any potential reconfiguration issues in the local environment? If you want to work directly with a support engineer or do a remote session, you should open a case from within the M365 admin portal.
