Question : Microsoft.Exchange.Search.ExSearch.exe 80% resources

In my windows task manager, I see that Microsoft.Exchange.Search.ExSearch.exe is taking about 80% or more resources. I did a search on this issue and the only thing that I found was something on excluding the Exchange folder from the antivirus scanner which I've done.

Any ideas?

hi

if you are using exchange 2007 or exchange 2010
then you may need to Rebuild the Full-Text Index Catalog

1.Start the Exchange Management Shell.

2.Remove the index directories that are associated with specified mailbox databases:its in the same location as you storage group
Run this command from powershell
ResetSearchIndex.ps1 [-force]  <dbname> [<dbname>]
3.Remove the index directories that are associated with all mailbox databases:
ResetSearchIndex.ps1 [-force] -all
