swbell.net email address

I have 2 swbell.net email sub accounts linked to my main swbell.net email address that no longer update. The red triangles says I need to sign in again to correct. The problem is first I can not sign out of the two sub accounts to sign in again. The second issue is that when I enter either of the addresses as the email address on my Currently sign in it only changes the password for my main account only.
