I have Samsung Mail linked to my Microsoft Exchange mail account. About 50% of the time the "Accept Invitation" will respond to the inviter, and the other 50% Samsung Mail will not send a response. If I close and reopen Mail I "usually" can respond again and Mail will send the correct response to the invitation.
I also have Outlook on my S24+ and that will send a response 100% of the time. Unfortunately, I like the other features of Samsung Mail better.
I have unlinked and relinked and that made no difference.
