Error message setting up SMTP with O365 email address

Hi, I am trying to connect my new business email (which I got through GoDaddy in Email Essentials) to existing Gmail and Outlook accounts however I keep getting an error message in both my current Outlook and my Gmail accounts. 

The out look error says:
failed to authenticate to the server '' port '587'. Please verify your credentials


The gmail error says:
Authentication failed. Please check your username/password.
Server returned error: "334 VXNlcm5hbWU6 334 UGFzc3dvcmQ6 535 5.7.3 Authentication unsuccessful [] , code: 535"

The username and password are both correct.

I have changed the password and retried with no success.

I have tried different ports with no success

I have spent hours searching online and can't find a fix.  


Any help would be greatly appreciated



Hello @SunnyP ,


Sorry for the late response, and welcome to the Community! To help get you a resolution, can you please confirm that when you go to and enter your Godaddy email address and the password that you can successfully log in to the email account?

That is correct, I am able to log into the account
