We have a Windows SBS 2003 Server that is running Exchange 6.5 that is dismounting the mailbox store on a regular basis. The temporary solution is simple in that we can remount the store and in continues to work for a couple of days. Does anyone know how to resolve this permanently?
P.S. I've looked into the issue a bit and I believe that it might be due to the size of the Mailbox store as I believe 18GB is only permitted unless you have a certain service pack level, or the setting is specified in the registry. We have tried both these fixes but the Store still seems to dismount.
Any assistance would be greatly appreciated.
