I’ve had a user telling me that when people send them meeting invites the sender is getting a bounced email saying that some other user can’t be reached due to an account not existing. Which it’s true the bounce back is for an account that was deleted, but why is there even a bounce back? I’ve pasted the error below.
Essentially what happened was there was an old user account that the existing user had given delegation rights too in outlook. I removed the delegation rights and it cleared things up.
This issue was especially annoying since there wasn’t any real indication of where the issue was really happening. GRRRR! Stupid outlook delegation rights.
