I have a user that when a calendar invite is sent to them it goes directly to their calendar as tentative which is fine but they never receive a message in their inbox. I am running Exchange 2013 CU7.
This is what I have tried so far but it has not helped. I disabled activesync and closed out of Outlook, but I see the same symptoms in OWA. I verified that the user has no rules or delegates. I changed the Mail Option so it does not Automatically process
meeting requests and responses to meeting requests and polls. I did a couple of message traces and they look like any other message being processed. I tried to set this command on the mailbox "Set-MailboxCalendarSettings –identity Mailbox
-AddNewRequestsTentatively $false" but it would not let me since it is not a shared mailbox. The calendar repair assistant is turned on for all of our users. I am thinking about moving the users mailbox to another database to see if it makes
a difference. If that does not work then I feel my only options is to export the users mailbox to as pst then import it into a new mailbox.
Is there anyway to get details on how a message is processed by the exchange server, so that maybe I can see why they are going straight to the calendar?
