UserA" has sent a meeting request to "UserB" and ""UserC" "UserA" has sent a meeting request to "UserB" and ""UserC" but ""UserB" is able to accept or decline the meeting requests but ""UserC" is not able to accept the meeting request he is getting the error as "As the meeting organizer, you donot need to respond to the meeting" but that he is facing this issue for only one particular reoccuring meeting request from that "UserA". If "UserA" sends a new test meeting request to ""UserC" he is able to accept the same, but the issue is there for only one particular reoccuring meeting request from that particular sender We have checked the delegations of "UserC" and no delegations has been set on the same and also we have tried by reinstalling the outlook on user system but still the issue has not been resolved
