Do you know what would cause the searches to fail on Exchange 2010 databases ?
Users are reporting that they are unable to find all items during a search. Helpdesk knows how to fix the problem by recreating the search files or to go around it by building new a database and copying the mailboxes. However we are trying to find out what is causing the frequent corruption. The Exchange server is Exchange 2010, Trend Micro Scan Mail for exchange mail filter, code two pro signature and Symantec Backup Exec 2015 remote agent also run on the server.
This link is a discussion of similar problems with DAGs and one user traced the problem to an anti virus product.
