You can try moving the mailbox to another E2K3 database. That usually fixes any problems -- if the move is successful. If the move fails you can run "isinteg" on the database. If the move continues to fail you can export the mailbox to a PST and then import it into the target database. >Can the .edb and .stm files get corrupt at the time of move Sure, just the same as they can during any operation -- sending mail deleting mail, receiving mail, etc. >what are the risk involved at the time of moving the mailboxes The most common problem is not haveing a sufficient amount for space on the target server to accomodate the volume of mail that's being loaded into the database. >and what are the different backup scenarios That's a complicated question because you're asking about both Exchange and the Active Directory. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
