Hi, All of a sudden my Application Event Viewer is getting flodded by Event ID 1173: Error 0x6bb deleting unused restricted view from folder 1-130CC1 (this value changes with every event)on database "First Storage Group\Mailbox Store (ServerName)". Microsoft Exchange Information Store will try to delete the view again at the next maintenance interval. This started happening this morning around 9am, repeated itself at 11am and then again at 12:30. I found one KB article which basically said not to worry about it. I wouldn't worry about it ifthe errordidn't keep coming up. Can someone explain to me what this really means and if there's something I can do to prevent the warnings from coming up? Thanks, J
