Ok Here goes, last weekend we upgradedthe exchange server from 2003 to 2007, during one of the bulk mailbox moves the server complained of hard drive space running out, so my other colleague decided to start deleting some ofthe old temp files & old transaction logs etc.. he mananged to also delete the ed0 file for the second storage group (how i dont know as i thought this was restricted), this then killed the mailbox move and corrupted the 3 mailbox databases, after around 3 hours of running isinteg's etc.., the storage group was back up and running, the trouble is the mailbox database that died whilst in the middle of the move, has lost all of the other users old emails, calendars, folders. I can see that the edb file still has them stored but it still cannot find them, i have ran isinteg -s Server -fix -pri -test alltests and it said it repaired the error, but still no joy, i also tried moving the mailboxes to another storage group to see if that would fix the problem. Is there anything i can do to get the mailboxes back to their original state, i could restore on the exchange 2003 box, but that would mean they would loose 3 weeks work. Any help would be greatly received
