Meeting failed when adding recipient to existing meeting

Copper Contributor


I have one user that if i create a meeting with a example 3 recipient then send it and after that open the meeting and add another recipient I'm getting an bounce error from the Exchange Server.

Tried to run the test in OWA and I don't see the problem.

Tried to install a new pc with new outlook, and the problem is still there.


Please help
