Hi, anyone knows any thing abut Event 9774? i cant find nothing online. How can i find a spesific mailbox FID in exchange 2007? RRD

Can you post the exact error message? Isinteg in test mode dumped to a log file is what is used typically to match up a FID.

sorry, was away for the week. this is the exact error message- Corrupt Message detected. Fid = 1-2BF39AD61D ; Mid = 1-2DF54BA848 ; Some or all properties of this message will not be transferred correctly. thank you.

Ok, isinteg running in dump mode can help you locate the folder name by searching in the log file. http://technet.microsoft.com/en-us/library/bb125144(EXCHG.80).aspx If you locate the mailbox that is affected by this, the easiest way to fix typically is to move the mailbox to another store. If however, you are seeing a lot of these, then you may want to consider running isinteg in -fix mode for alltests. In that case, the general recommendation is run an offline defrag then isinteg in fix mode until they are no errors. (Typically it takes 2 or 3 times). During this time, the store is offline. And if you decide to this, take a full backup before and after A similar case: http://social.technet.microsoft.com/Forums/en/exchangesvradmin/thread/9dc63659-c74b-42e3-a0a6-11f3127bb8b1 Hope that helps
