I have a setup where Out of Office messages, Read or Delivery receipts don't seem to be delivered...
There is a group set up with 'send as' permissions granted to some people (in fact the members of the list can send 'from' the list). If someone sends a message 'from' the group to someone else within the same Exchange environment who has an Out of Office set up, the OoO does not get returned. Neither do they get a Delivery Receipt or a Read receipt if they request it...
Normal replies to the message get delivered but any Out of Office replies are not. Messages direct to the recipients (not 'from' the group), behave as they should.
It is possible to do a message tracking and see the OoO or Read Receipt get to the categoriser - and that's it, it does not reappear.
This is with E2K3 SP2 and Outlook 2K3
Any thoughts, ideas or wisdom?
