Now you contact your mail provider and work with them to see if any server has blocked this. It's called black listing and only those that encounter this the first time will think it can be solved in a forum.

MS in it's wisdom, updates WLM "on the fly" without notifying or asking you. Sometimes these updates cause problems, so you have to uninstall and reinstall. When you do, be sure to export your email and contacts first so you don't lose them. I had to do this back in April; fortunately I haven't had to since.

Good luck.
