Outlook connecting to BTMail on Mac

[Margot25]

Have always used Outlook Client to download email from BT webmail.  Suddenly stopped connecting.  My login works to get me onto webmail but is rejected by the Outlook client returning an error message 'cannot connect to server'.

Help!  Thanks in advance

Are you presently a BT Broadband customer or are you paying for your email through a BT Premium email account or did you migrate to EE Broadband?

If none of the above your email account may have been downgraded to a BTMail Basic account which can not be used with an email client or email apps.
