  2. In the Internet Accounts window, click on the Add button and select Mail.
  3. In the Display Name field, enter your name or your company name as you would like it to appear on your outgoing email, then click Next.
  4. If you are using Outlook Express version 5, you will be asked to use an existing address or sign up for a new one. Select I already have an email address I'd like to use. The option to sign up for a new address is not presented in Outlook Express version 6.
  5. Enter your email address. This may be:

    • yourname@btclick.com
    • yourname@btconnect.com
    • an email address which uses a domain name you own, e.g. yourname@yourcompany.co.uk/.com/.net

  6. Click Next. The next screen should show 'My incoming mail server is a POP3 server'.
  7. If you are using an email address with @btclick.com, @btconnect.com, or a domain name which we host for you, enter outlook.office365.com in the Incoming mail server field. Otherwise, you will need to ask the company which provided your email address what to enter here.
  8. Enter smtp.office365.com in the Outgoing mail server field. Click Next.

    • If you entered something other than outlook.office365.com for the incoming mail server in the previous step, you will need to ask the company which provided your email address what to enter for the account name.
