Noticed a few rogue SIDs (S-_-_____--______)  in Exchange/Windows that I think may be for old accounts that were removed. How can I check to see if they are in use and if I can safely remove them?

if you see the SID, it means the account was deleted.  i just remove them when i find it since it doesn't match to any account

I would just leave them alone. Removing SIDs that you can't identify can break your system. Some of them may be related to Windows before it joined the domain.
