Q. What do I do if I am getting the 550 Relay Error Message in Microsoft Outlook?
If you are receiving the above message or a similar message that has the words "550 Relay Error" in it, please follow these directions:
Click the Tools menu.
Click on "E-mail Accounts" at the bottom of that menu
Click "View or Change Existing Email Account."
Select the account you want to change and click it. Your email account should say something like one of these:
Click "More Settings."
Click the Outgoing Server tab.
Check the box that says "My outgoing server requires authentication."
Now you should see the previous screen again.
Click Test Account Settings.
You should see the program processing, then all green check marks.
If you see anything but green check marks don't close anything and call Agent Image 1-800-492-6777
If you don't have the time to call click close or stop on the test account settings
Then click next
Then click finish
This saves the new changes you made and that is the most important part. Sometimes after you save the settings it will work so try to send a message... if it still doesn't work... please call as soon as you can.
If you see green check marks then click Close.
You should see the previous screen again, click Next then Finish.
Then click "Send/Receive" in the main window and you should get any new messages you have.
