Calendar invites getting deleted before they reach mailbox

One of our executives is experiencing an issue where when he has people with delegate access of his calendar, meeting invitations are being deleted before they reach his inbox as per my mail trace searches. The log shows that a rule deleted the invite before reaching his mailbox, but i have already ruled out inbox rules as we have deleted the few that he had, and i checked everywhere for hidden or corrupted rules. The meeting invites operate normally when nobody has delegate access to his calendar, but his PA needs to have delegate access so she can manage his schedule.

I have checked with the user and there are no auto accept or decline settings – the issue is purely reliant on them having a calendar delegate. As noted earlier in the ticket, I have already cleared out any junk rules with MFCMAPI and the issue persisted afterwards.

Could this be a result of the calendar delegates having automated accept/decline settings?

    I have an similar issue, we have a EA with delegated exec permissions. Recently she received invitation on behalf of the exec from Google Calendars. Using message trace I see that invites are deleted before reaching inbox as invitation. In this case the EA receives all the emails saying meeting is cancelled and the invitation. Still looking for a fix.
