I have it configured to delete on exit and get the dialogue with "Do you want to permanently delete.......". Its after that the other box appears and then outlook closes - without giving me time to see what it is!
Every time I leave outlook it seems to pop up with a dialogue box and then closes. Unfortunately it happens so quickly I cant see what the box is telling me.
I have looked to see if there is a stuck read receipt in the mailbox but there isn't.
Does anyone have any other ideas what it may be...
