I had a virus on my windows 2003 server. It was sending out MASS emails most of which were coming back to the bad mail folder. I have removed the virus, but in the meantime the bad mail folder was filling up. The only thing I could do was to rename the folder. Before I had finished removing the virus I had 2 folders that were renamed with thousands and thousands of files. I have tried all the normal rmdir, del *.*, ect all that seems to do is lock up the server. The REAL problem I have is the only way I can access cpu is by remote access. Is there a way in DOS to delete files in batches "something like delete 1000 files at a time". Any help on this would be great. I hope all this makes sense.Have you tried BadMailAdmin?

I once fixed a "Can't send email" problem for a customer, because there were over 10,000 OLD emails stuffed in the Sent Items folder.
I just tracked it down in Windows Explorer, right clicked on it and hit DELETE. In just a few seconds, the folder was gone and the problem was solved.
The email program remade that folder the next time it ran.

Good Luck,
