Exchange 2007 Event ID 447

Hello,
      I have found some errors in our Exchange 2007 server signaling corruption. In the Application logs it shows many Event 447 ESE errors. Everything seems to running fine but I want to make sure we are ok. We have 2 databases and the errors are reporting the corruption on database 2. It appears that this has been going on for several days so I do not want to do a restore from backup unless I absolutely have to. This db is about 100GB in size. Is it feasible to create a third database and move the current mailboxes from database 2 into database 3 one at a time? Would exchange check the integrity of each mailbox as it is moved and do you think this is a viable solution?

This is the error:

MSExchangeIS (4220) Second Storage Group: A bad page link (error -327) has been detected in a B-Tree (ObjectId: 37, PgnoRoot: 86) of database D:\Exchsrvr\SG2\MDB2.edb (7391395 => 7391389, 5394274).


Thank you in advance.

Moving mailboxes to a different database will fix any inconsistency as all items are moved one at a time. On the other hand, if an error is found the move will skip the corrupted item. If you want 0 loss, I would set the skip limit to 0. This way the mailbox wont be moved unless all items are good.

I have started migrating the mailboxes and everything seems fine so far. Thank you.
