I have read most of the posts regarding memory leaks and the ones that discuss store.exe, but none of them seem to work for me. I have a 5 user Unity system with 5 User Exchange 2000 on the same box. Unity seems to stop responding when store.exe gets above 500MB. Today it is 588MB and and Unity stopped responding. A simple reboot always seems to take care of the problem. The server has a 1GB processor with 1GB RAM. Any ideas?<br><br>
