SMTP not working on outlook 2010 - cannot send emails from outlook even though I can receive them

I have outlook 2010 and have previously had all my BT email accounts using POP.

However, I can no longer send emails as it does not recognise the authentication, even after using SSL and port:465 as requested. In the settings section below. So while I still receive all my emails, if I want to send an email using my BT email, I have to use BT webmail, which is a pain and not ideal. 

I have even tried setting up using IMAP and get the same issue. Inbound emails arrive ok, but I cannot use outlook to send.

I've started to use a different mail client as a result. However, if BT can fix this problem, then I will revert to BT email. It is a show-stopper.

 

What are the settings for outgoing and incoming BT Email servers?
 

IMAP and POP are the protocols or technologies that enable you to download your email messages to your computer or device.

To find out if you're using IMAP or POP, open up your email program, highlight the mail account you want to find out about, then open its settings or properties. Look to see whether the Mail Server "type" is set to IMAP or POP.

  • IMAP always syncs with the BT Email server, so any changes you make in your email program will also appear in your webmail inbox
  • POP3 doesn’t sync with the BT Email server so changes you make in your email program will not be transferred to your webmail inbox and could be lost

So if you're going to regularly use webmail and an email client, we'd recommend using IMAP with SSL enabled.

  • SSL (Secure Socket Layer) ensures that all data exchanged between your email client and the BT Email server is encrypted making it almost impossible for anyone to steal your username or password

 

To protect our email server from abuse by spammers, we also require all emails sent through our email service to have SMTP authentication.

  • SMTP (Simple Mail Transfer Protocol) is an authentication process that identifies the origin of emails; it stops them being sent anonymously and therefore helps to combat spam

Enabling SMTP authentication is easy; you usually switch it on by ticking a box called "My server requires authentication" in your email program's settings. If you don't set up SMTP authentication, you'll get an error 530 failure message when trying to send email messages.

 

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 won't work.

If your IMAP client supports it, we recommend you also set up the following folders:

  • Trash
  • 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

How do I set up BT Email on my computer or mobile device? >

Are you a BT Broadband customer or paying for your email through a BT Premium Email account?

I used to be a broadband customer but I am a BT mobile customer.

I don't see why customer type would effect how outlook should work?

It does. Unless you have a BTbroadband contract or paying for Premium mail, your mail service will have been downgraded to Basic which is only available as webmail not via clients such as Outlook.

If you are no longer a BT Broadband customer you will have been downgraded to BT Basic which can only be accessed via a web browser and not by email clients/app.

An email account is not part of the BTMobile package. You only get a BT email account as either a BT Broadband customer or by paying for it as a BT Premium email customer.

See link about BT basic.
