I suddenly have a huge problem with my Exchange Server where the Information Store keeps crashing and after some investigation have seen that my store has grown to a staggering 74GB! I changed the registry setting to 100GB to allow some work around and to move some mailboxes to a different store.
While attempting to reduce the size by deleting several Mailboxes and moving them to a different store (on the same server) the Information Store keeps crashing every 10min or so. Trying to do a full backup also fails so that I can purge the deleted boxes and reduce the size.
It seems I'm stuck in a dead-end because I can't keep the store online long enough to reduce it's size. Is it closing the service because of the built in 75GB limit?
Please help urgently? How do I keep the store on-line again?
There are no significant error logs in the log viewer so I have no idea where to go from here...
