We have an organization with 6 Exchange Servers Mailstore Servers running in a DAG format. We have recently run into a situation where we are trying to run a Discovery search in the organization and keep getting "Search Folder Time out" with the searches.
We have tried with "one" phrase and one mailbox to be searched. We could get that to work intermittently. But whenever we try to do a search with 3 terms and 8 users in the TO and FROM fields we get the "Search Folder Time Out" error. In the event viewer we get the error 3003 Discovery.
We have recently upgraded to SP3 and Roll Up 1 on the servers. We have 15 servers total in the environment. We were able to do this before, but now we are unable to do the searches. This is critical as we have to do these searches all the time. Any help will be appreciated.
