I have exactly the same issue - it’s a complete disaster. I travel regularly for business and can’t rely on being able to access emails. I end up in a two factor authentication loop that never ends. The system doesn’t remember my devices, asks me where to send authorisation codes, then when I have done all that, and when I try to log into webmail (which at one point BT advised me to do whilst travelling) it sends me back and asks me to log in on with my BT ID which restarts the whole process. It’s a complete nonsense. I only re-contracted my very expensive broadband with BT to ensure continuity of my email, but what I am receiving is continuity of problems!!
I also don't know what to do. I have been told that “the BT email is only really for use in the UK” by a helpful operator from the support team. How can BT purport to be a global business if it can’t get email to work!!
