Key Facts

What is an Email Signature?

An email signature is a block of text or an image that is automatically appended to the end of your outgoing emails. It typically includes your name, title, company, contact information, and sometimes a company logo or a disclaimer. In Microsoft Outlook, creating and managing signatures is a straightforward process that can significantly enhance your professional communication.

Why Use an Email Signature?

Using an email signature offers several benefits:

How to Add and Manage Signatures in Outlook (Desktop App)

The process for adding a signature varies slightly depending on whether you are using the Outlook desktop application, Outlook on the web, or the Outlook mobile app. Here’s how to do it on the most common platform, the Outlook desktop application for Windows:

  1. Open Outlook: Launch the Microsoft Outlook application on your computer.
  2. Navigate to Options: Click on the 'File' tab in the top-left corner of the Outlook window.
  3. Access Mail Settings: In the File menu, select 'Options' from the left-hand sidebar.
  4. Go to Mail Settings: In the Outlook Options window that appears, select 'Mail' from the left-hand menu.
  5. Find Signatures: On the right side of the Mail settings, look for the 'Signatures...' button and click it. This will open the 'Signatures and Stationery' dialog box.
  6. Create a New Signature: Under the 'E-mail Signature' tab, click the 'New' button.
  7. Name Your Signature: A pop-up window will ask you to name your new signature. Choose a descriptive name (e.g., 'Work Signature', 'Personal Signature') and click 'OK'.
  8. Compose Your Signature: In the 'Edit signature' box below, type the content you want in your signature. You can format the text using the toolbar above the box, similar to using a word processor. You can change fonts, sizes, colors, add bullet points, and insert hyperlinks.
  9. Add Images (Optional): To add a logo or other image, click the image icon in the toolbar and browse to the image file on your computer. Ensure the image is not too large, as it can make emails cumbersome.
  10. Set Default Signatures: Below the signature editing box, you will see dropdown menus for 'E-mail account', 'New messages', and 'Replies/forwards'. Select the email account you want this signature to apply to. Then, choose your newly created signature from the dropdown for 'New messages' and/or 'Replies/forwards' as desired. For example, you might want a full signature for new messages and a shorter one for replies.
  11. Save Your Signature: Click 'OK' to save your new signature and close the 'Signatures and Stationery' dialog box.

Managing Multiple Signatures

Outlook allows you to create and save multiple signatures. This is useful if you have different email accounts within Outlook, or if you want different signatures for different types of communication (e.g., a formal signature for clients and a simpler one for internal colleagues).

Outlook on the Web (Outlook.com / Microsoft 365 Web Access)

The process is similar for the web version of Outlook:

  1. Log in to Outlook on the web.
  2. Click the Settings icon (gear symbol) in the top-right corner.
  3. Select View all Outlook settings at the bottom of the settings pane.
  4. Go to Mail >Compose and reply.
  5. Under the 'Email signature' section, click + New signature.
  6. Enter a name for your signature.
  7. Compose and format your signature in the text box provided.
  8. Use the toggle switches to select whether to automatically include your signature on new messages and/or messages that are forwarded or replied to.
  9. Click Save.

Outlook Mobile App (iOS and Android)

Mobile signatures are typically simpler:

  1. Open the Outlook app on your smartphone or tablet.
  2. Tap your profile icon or initial in the top-left corner.
  3. Tap the Settings icon (gear) in the bottom-left corner.
  4. Under 'Mail', tap Signature.
  5. Enter your desired signature text. Note that formatting options are very limited on mobile.
  6. The signature you create here will be automatically added to all outgoing emails from that account on your mobile device.
