Our organization has a single exchange 2010 server for our ~100 users. I was recently asked to go and do a search for all mail related to some specific key words, and I sorted out how to use Discovery Search Mailbox for multimailbox searches, and it pulled up a ton of hits. But there were seemingly some missing pieces.
If someone deletes an email permanently, does the Exchange server continue to keep up with it in some fashion? If not (by default), is there a configuration or trick to do this? Is 'archiving' what I'm looking for?
