Hi, all my exchange servers go under online defragmentation in "random" hrs... Last night my server 1 went through an online defrag and dismounted mailbox stores.
here is ..straight from the log ....
"" Information Store (4776) Third Storage Group: Online defragmentation of database 'Y:\Exchsrvr\mdbdata\Mailbox Store 12.edb' was interrupted and terminated. The next time online defragmentation is started on this database, it will resume from the point of interruption. .....""
although it is scheduled to start Saturday night at 11:00 pm it did last night. any ideas , why ??
