I get the following error when attempting to send a message iIn Outlook 2000. The error message is "The messaging interface has returned an unknown error. If the problem persists, start Outlook again." I am using wordmail(Word is my email editor). I have a graphic in my signature and use a theme(stationery). Usually when I get this error, I just click "send" again. Sometimes it sends and sometimes I get the error a couple of times. It always seems to send eventually. The resulting email will have attachments that appear to be either my signature graphic or the theme's background tile. The number of attachments appears to be related to the number of times I get the unknown error. Has anyone else experienced this problem or better yet, does anyone have a solution?
