We couldn't authenticate with the credentials provided. Please try again.

Hi,

Connecting to Exchnage Online I get this message "We couldn't authenticate with the credentials provided. Please try again." I am using the correct password and the email address "[email protected]". Be gentle with me. I'm interested in analysing data and really don't understand, or want to understand the tools I'm using to connect any more than I'm interested in my car's transmission system.

We have recently implemented 2 factor authentication. I ensure that the Microsfft account side-tab is logged in. 

The response appears fairly generic and might cover a thousand different reasons 

Can you help please?
