I think my exchange server is missing some vital files, it is not mounting the store and I am not getting any m drive. I got this message from event viewer any suggestions on how to proceed would be appreciated. I also restarted services and rebooted with no success Information Store (2720) Database E:\Program Files\Exchsrvr\mdbdata\priv1.edb requires logfiles 41685-41688 in order to recover successfully. Recovery could only locate logfiles up to 41687. Thanks Jeff
