After noticing dozens of Event ID 1025 entries in the APP log of our (single) Exchange 2007 SP2 mail server, I ran ISINTEG (output below) to fix any problems. This was on Saturday, August 13th. Today, I noticed more Event ID 1025 entries (once again, several dozen). I have had to run ISINTEG once or twice before (several months ago, so not that recently). Besides running ISINTEG again, is there any way to determine: 1) What is causing these warnings? 2) What mailbox is triggering these warning - assuming it is a single mailbox? Here is the output of ISINTEG from August 13th: [PS] C:\>isinteg -s MailServer1 -fix -test alltests Databases for server MailServer1: Only databases marked as Offline can be checked Index Status Database-Name Storage Group Name: First Storage Group 1 Offline Mailbox Database Storage Group Name: Second Storage Group 2 Online Public Folder Database Enter a number to select a database or press Return to exit. 1 You have selected First Storage Group / Mailbox Database.

An older thread indicated this problem was related to the Exchange search; it recommended rebuilding the Full Index Catalog http://social.technet.microsoft.com/Forums/en-US/exchangesvrgeneral/thread/d546af02-acc6-4d5b-a8d4-8e586d7b7034TBrennan

Hi Le, Go through your question, I get some suggestion for you: 1) Run isinteg on database 2) Move mailboxes to news tore 3) Mount stores with blank database and use dial tone strategy to merge emails Hope it helps.Best Regards!

Thanks to both for your suggestions. Rowen-Xu: I did run ISINTEG (and ESEUTIL /G for that matter) and everything was either OK or, if there were errors, fixed. I will try rebuilding the Full Index Catalog and if in the future, the problem persists, I will try moving the mailboxes to a new store.

Hi, Thanks for your coorperation. Any new information you can update here.Best Regards!
