I have a strange thing going on. I am running Exchange 2003 standard with SP2. All of a sudden over the past two days, at exactly 5am in the morning, Exchange dismounts the mailbox store saying I am over the 18g limit? I thought with service pack 2 that it was increased to 75g? Anyway, I can go into system manager and simply remount the store and it does without problem. My fear is that every morning at 5 am it will keep dismounting for some reason. It has happened 2 days in a row now. Any thoughts on this? Thank you!
