Internal Office 365 users are recognized as external

Hello,

When I send an email to an Office 365 group, it returns a message that the user is external and does not belong to the organization, but it does belong.

  • Try to provide some more details, we're not mind readers here. Are you in Hybrid? Where is the user's mailbox located? How is your mail flow handled? What does a message trace show?
