Strange problem this and one that does not seem to be fixed by the wonderful google.

I have several BT Connect emails at work and have recently purchased new Nokia 520 for those users.

Trying to set their email up on the phone. It will not sync and says the password is incorrect.

This is trying via the advanced option on the phones and using the office365 setup instructions.

Google comes back with several sites where people have had problems but I have not been able to find one that comes up with a solution.

Any help would be appreciated.

So is it BT or office 365? WP is quite clever in finding out proper connection info by itself, often email and password is enough. BTW do they use a two step authentication? If you use it with outlook.com, you have to generate an app password and use that one instead. Mail app itself does not support the codes. You may need something similar for BT accounts if it is on. Also try posting on MS forums, you will get better answers there.

The BTconnect system now uses Office365. You can connect fine with login and password via the web interface.

Setting up the email as other account and using the credentials you get the same problem, tries to sync and then says the password is incorrect.

I'm pretty sure the passwords and logins are correct as I have tried a different user on another phone and the same error occurs.

I'll try the MS forums, thanks
