Outlook error 550/Administrative prohibition fix.


MS Outlook sometimes comes up with a error 550, Administrative prohibition, or 0x800CCC69 error message.  It has to do with proper authentication.  The solution is to authenticate before sending your emails. Just check the box as seen in the picture below.

Believe it or not you can actually send email without logging into the server first. That is a bad idea, so this box says that you must log into the server first.
