2.  Outlook on my desktop - can receive emails, can send emails to my staff internally
3.  PROBELM "CAN NOT" send externally - keep getting an error message....see below:

Hey tamms,
Welcome to the BlackBerry Support Community Forums.
Since it seems like this is not a BlackBerry issue, I would suggest you contact your mail provider to find out if they can resolve this issue for you.
