One of our users has been sent approximately 300000 messages over the last couple of days from the same person and the same content. These are now being blocked on the AntiSpam server, however I am looking for a way to mass delete these messages. Outlook appears to have a limit to delete 4000 messages at a time.
I have tried Exmerge and it appears to do about 10-15000 messages before getting errors in its log and I have to restart.
ANy other suggestions to Mass delete these messages?
