Problems With backup Exchange 2010 databases

Hi I'm having a problem with backing up our exchange databases through DPM.

Currently when our databases are being backup we will receive one the following error messages in DPM.

"Data consistency verification check failed for <DatabaseName>.edb of Exchange Mailbox Database <DatabaseName> on <MailServername>. (ID 30146 Details: Unknown error(0xfffffb4a) (0xFFFFFB4A)"

OR

"Data consistency verification check failed for LOGS of Exchange Mailbox Database <DatabaseName> on <MailServername>. (ID 30146 Details: Unknown error(0xfffffe0b) (0xFFFFFE0B)"

Now DPM advised I need to check the version's of eseutil.exe and ese.dll what I have done to make sure they are correct on the DPM server and match what is on the Exchange server. This hasn't seemed to have fix the problem.

I can get the databases to backup and truncate there logs if I change the eseutil options within the protection group to not run Eseutil to check data integrity" but this isn't a solution to my problem.

Can anyone help??

Thanks
