I set up through outlook for my work email to be redirected to my BB. From the BB I can email anyone except anyone with my work's extention. Why is this happening? It sends but no one receives anything.
When you send an email to your internal domain what service book is being used?
To check, open the last sent message (which a checkmark on it) and scroll to the very top of the message. It should say "Sent Using:" What does the rest of it say?
