Outlook Mail on the Web can append a signature to all emails you send automatically.

Why Would I Want a Signature for My Emails?

A signature is a smart thing to have at the end of an email: it can tell the recipient about your name, title, company, website, and whereabouts in one place. Once set up, it will do so automatically to boot as Outlook Mail on the Web (Outlook.com) appends the signature block when you start a new message or reply.

You can set up but one signature in Outlook Mail on the Web, but doing so is easy, and you can add rich formatting with little effort as well.

  2. Select Options from the menu that has appeared.

  3. Go to the Mail | Layout | Email signature category.

  4. Enter the signature you would like to use under Email signature.

    You can use the toolbar to apply formatting and insert images, for example. Outlook Mail on the Web will convert the formatted text to plain one if you send a message using plain text only.

    It is best to keep your signature to some five lines of text.
