How about the erorr message "you do not have permissions to send email 
to the following recipients..." from Exchange server " ? It may happens 
when :
- remote mail server fails
- recipient name is incorrect
- more that I do not remember

If you go to Google, type in "exchange you" then the drop-down box will 
show that message immediately.
