Correct Credentials needed

[Peter0303]

I am trying to use btmail on my Samsung tablet. I already use my email successfully on my Lenovo desktop (android/windows) and on my Samsung phone, A41, but on the tablet I get the  message "correct credentials needed". My username and password are corect so what else am I missing?

Thank you

Peter
