Recently I have had some strange issues with Exchange so we ran the following command:
isinteg -s servername -test alltest
This ran through and found 22 erros. I ran the test again as you should and it came up clean. I am now getting the following errors regularly throughout the day:
Source: MSExchangeIS Mailbox
Catagory: Background Cleanup
Event ID: 9792
Cleanup of the DeliveredTo table for database 'First Storage Group\Mailbox Store (RMSERVER)' failed with error -1017. 0 entries were purged before the failure was encountered.
I think my only option may be a hard repair (Eseutil) but am aware this can delete data. Just wondered what everyone else thought.
