I've been trying to create my BT Mail email account however I get the following message when I try:
There isn't a BT Yahoo! Mail service associated with the username/email address you've entered.
If never been given the option to create one so I'm not really sure what to do.
Has anyone else experienced this issue before?
To set up a BTMail email address you need to first of all have a BTID.
Once you have that you can then access your "MyBT" and MyExtras" which will allow you to "Mange MY BTMail" where you can then set up a BTMail email address.
