Thanks for the suggestions. As for moving the mailboxes, that too is a problem: http://social.technet.microsoft.com/Forums/en-US/exchangesvradmin/thread/90a71002-8f18-4323-8751-70ea2443ab2e Will keep on looking at this.

What do you do when ISINTEG reveals application level errors (right?) in your Exchange database but... cannot resolve them even after running this command several times?

Thank you for the reply and the references. They will be useful once I complete my transition to E2K10. Currently, however, EX10 is still running E2K7. I should have indicated that.

If ISInteg is not able to resolve the erros . I would Create a new database and move the users. Which in turn will have complete new intenal structure in the new store.

Will try. Also having problems moving some of the mailboxes - possibly due to permissions problem.

1. Isinteg log shows 0 fix 0 warning indicating that there are no errors in the information store that you specify. 2. Please check the application log if there are any logs with source ESE pointing to any database corruption . 3. Please run eseutil /g to perform deep integrity check on the database. 4. Please check disk space on the server. 5. Please run chkdsk in read only mode and see if it shows any errors on all the drives/partitions on this server. Please find some useful links for your reference about how to move the mailboxes from Exchange 2007 to Exchange 2010 http://markswinkels.nl/2009/11/how-to-migrate-from-exchange-2007-sp2-to-exchange-2010/ http://blogs.technet.com/b/schadinio/archive/2010/07/20/exchange-moving-mailboxes-exchange-2007-vs-exchange-2010.aspx http://technet.microsoft.com/en-us/library/dd298174.aspx#Bas Girishp

1. Isinteg log shows 0 fix 0 warning indicating that there are no errors in the information store that you specify. There is one test which still reports errors as shown below Test Folder result: 501 error(s); 1613 warning(s); 0 fix(es); 2009 row(s); time:0h:0m:0sJasjit Singh Dhindsa | ITIL v3 | IASA Foundation Certified | MCITP: EMA 2010/2007 | MCTS: MES 2010/2007, OCS 2007 | MCSA: M+S | MCSE: M+S

If after running Isinteg multiple times you are unable to reduce the error count, you can consider that database not fit for a production environment (at which point you should take the necessary steps to move the mailboxes to another store).

As of Exchange 2010 the well-known IsInteg tool was dropped. New-MailboxRepairRequest can be used to detect and fix mailbox corruption, per mailbox or per database. This functionality is an improvement over IsInteg The syntax of New-MailboxRepairRequest is as follows (left common parameters like Confirm and WhatIf out): new-MailboxRepairRequest [-Mailbox | -Database ] -CorruptionType [-DetectOnly] [-DomainController ] Please find below articles for your referance http://eightwone.com/2010/06/14/goodbye-isinteg-hello-new-mailboxrepairrequest/ http://www.more2know.nl/2011/01/27/exchange-2010-sp1-database-integrity-checking-new-mailboxrepairrequest/ GirishP
