I have a 2000 sbs server running exchange 2000. Users complained that they could not "connect" to the exchange server. After I looked in the system manager, I noticed that the "mailbox store" was not mounted. I right clicked on the mailbox store, and mounted the volume. It mounted successfully, and some users found themselves in a "connected" state... but only for about 20 seconds, and then the mailbox store would dismount. I cannot keep this volume mounted, and therefore I am in a serious state of no email. Does anyone have any suggestions on how to fix this? Thanks
