One of our users, is doing an incoming message search with a keyword on his complete mailbox. At the end of the search GW shows all the results till a particular date (5-1-2013), but there must be more results, because he received more mails with the same keyword after this date. I already did a GW maintenance on his maibox and everything seems to be fine. So i can't figure out why GW won't show the rest of the incoming messages in the search. Any ideas?
