From a user perspective, this is probably the least desired possibility, although it certainly would avoid any further complications :) Another possibility would be to block any further attempt to SELECT, or add messages into the mailbox and queue the delete for the next time the lock is released. I know of one server that does this in certain circumstances, and it seems minimally harmful from a end-user and client perspective. -- Dave Warren http://www.hireahit.com/ http://ca.linkedin.com/in/davejwarren
