I don't really know where to begin but I have a user that received a email (notification) from 'spsadmin'. I am assuming this was an auto notification setup via workflow but for the life of me, I cannot locate that workflow!
I have searched in SPD and OOB workflows that are listed for the possible lists, libraries etc. but I don't see anything. The title of the notification states SP version history report... not sure if that can direct me somewhere.
