Hi @Tony Coaxum , I believe the error you are getting is either domain-related or transient. Users have reported that they made changes to domain registration, while other users said error was gone without any changes.

My suggestion: check that your user settings and domain are proper: user UPN matches between on-prem AD and Azure AD; session hosts are domain joined in supported configuration.
