hi, We are running exchange 2000 standard version with all sp3 and post sp3 patch, this morning it reached the 16 GB limit. since then we are unable to mount the database. searched the KB articles. Finally we decided to run the eseutil utility for offline defragmentation and then move some mailboxes to another server. i am curious to know, how much time it will take for offline defragmentation. its almost 5 hrs for me and its only 60% completed. i am worried if this works ? All the log files and .edb files are untouched. Any other solutions ? Any help would be highly appreciated. thanks !!
