Unable to Add BT Mail Premium Account

GeorgeLeonidou20 — Wed, 07 Jan 2026 15:46:12 GMT

Good Afternoon,

I am having major trouble adding a BT Mail Premium Account to Outlook Classic & Outlook New.

BT Support have advised that an App password is no longer relevant to the issue & that the issue is likely related to Outlook.

I Have however used the server settings provided by BT Articles and it continues to fail to connect.

IMAP settings

Incoming Mail Server: mail.btinternet.com

Port: 993, this should be automatically populated by selecting the SSL encryption

SSL Encryption: Enabled but not STARTTLS

Username: your email address including the @btinternet or @btopenworld.com part

Password: your btinternet or btopenworld password

Root folder/path:

Folder separator: . (full stop)

Please do not enable secure password authentication (SPA). It's not needed when you use SSL encryption and will not work.

Most clients will automatically set up the following folders. If not you may wish to do so:

Trash or Deleted
Spam or Junk
Sent Items
Drafts

POP3 settings

Incoming Mail Server: mail.btinternet.com

Port: 995, this should be automatically populated by selecting the SSL encryption

SSL Encryption: Enabled but not STARTTLS

Username: your email address including the @btinternet.com or @btopenworld.com part

Password: your btinternet or btopenworld password

POP from folder: by default, POP will pull emails from your inbox

SMTP settings

Outgoing Mail Server: mail.btinternet.com

Port: 465 (this may not be automatically populated on selecting SSL, so you'll need to check)

SSL Encryption: Enabled (but not STARTTLS)

Authentication: PLAIN

Username: your email address including the @btinternet or @btopenworld.com part

Password: your btinternet or btopenworld password

Any assistance or advice would be greatly appreciated.

Thank you.

I've just created a test account in New Outlook with no problem, I didn't need to enter the settings manually, just email address and password.

Are you sure your account is Premium Mail and not Basic Mail?

Good Afternoon Sir,

I am receiving the below errors :

Yes this is a Premium Account which is configured correctly but it still refuses to sync and repeatedly prompts for a password which I already confirmed is correct by logging into the webmail app.

Please advise further.

Thank you,

I think the email address is case sensitive and your logon is showing a capital 'L' instead of lowercase
