I have just installed Thunderbird, am continually getting "certificate for outlook.office365.com" not trusted. I have added Thunderbird to my Malwarebytes exception list, but the the notice continue to come. I have ensured that OAuth2 is the correct authentication method, but the messages persist.

Is there something else I can do to stop these messages?

Would be very grateful, thank you.

Sounds like your antivirus (not MWB) is intercepting the real cert. Which AV are you using?
