Authentication issue: User Principal Name does not match Email

[doctorjim]

I have added an Employee Center tab in Teams (ServiceNow for Microsoft 365).  Most users have no problem opening that tab, however some get the following error which seems to be due to the userPrincipalName (jdoe@us.blah.com) not matching the Email/User ID (jdoe@tx.blah.com) in the sys_user record.  We want to use the Email that already exists in the sys_user table for authentication.

Can the issue be resolved by changing the manifest file.  Below is an extract from my manifest.  Don't know if this would be the place to change from UPN to Email and what that would actually look like.

Any update on this one??

Hello 

Instead, have you tried using the below in your Identity Provider for SSO?
