Hiya, i have a problem..... I have a SBS 2003 server running exchange with 4 users. The pop3 connector in exchange is set to download from one global mailbox. Things have been fine until i was asked to edit the routing rules for the mailbox. When i edit the rules and click ok, the mmc crashes. In event log i get.. Faulting Application mmc.exe .......faulting module pop3connector.dll..... Since then i have installed...Server03 SP1 and Exchange03 SP2but neither has fixed the problem. I have searched the internet and found a couple of others with the same problem, but no-one seems to have a fix for the issue. Any ideas would be grateful as i have spent many hours troubleshooting this problem. Andy

For future reference...... I finally sorted out the problem. A user had been removed from the server some time ago. There mailbox had been used in some of the routing rules. When i went to edit some of the other rules and apply the changes it crashed the mmc because the mailbox didnt exist. I solved the problem by removed the global accounts completly and re creating it.
