I had to defrag 5 mailboxes group. The first two went great but the last three froze the Exchange Server everytime.
Here the command I did:
eseutil /d /p "E:\program files\exchsrvr\mailbox3\mailbox3.edb" /t"x:\transfer\mailbox3.edb"
I had to defrag over the Lan to another computer since there are no space available on the Exchange server.
I did not have any error message, on the screen or on the event viewer. I had to press the on/off to restart the server everytime.
Thanks for your help
