How To Update Email Signature In Outlook

Updating your signature in Outlook involves accessing the signature editor from the File menu or Settings. The exact path differs slightly between Outlook versions, but the core steps remain the same. Below, we break it down for each platform.

Update Signature In Outlook For Windows (Desktop)

Outlook for Windows is the most common version used in businesses. Follow these steps to change your signature:

  1. Open Outlook and click File in the top-left corner.
  2. Select Options from the left-hand menu.
  3. In the Outlook Options window, click Mail and then the Signatures button.
  4. Choose the signature you want to edit from the list, or click New to create one.
  5. Type your new signature text in the edit box. Use the formatting toolbar to change fonts, colors, and sizes.
  6. Add images by clicking the picture icon. You can insert your company logo or a photo.
  7. Select which email account this signature applies to. You can set different signatures for new messages and replies/forwards.
  8. Click OK to save your changes.

That is it. Your signature will now appear automatically in outgoing emails. If you want to remove a signature, select it and click the minus sign.

Update Signature In Outlook For Mac

The Mac version of Outlook looks different but works similarly. Here is how to update your signature on a Mac:

  1. Open Outlook and go to the Outlook menu in the top bar.
  2. Select Preferences.
  3. Under Email, click Signatures.
  4. Select the signature you want to edit from the left panel.
  5. Edit the text and formatting in the right panel. You can also add hyperlinks and images here.
  6. To set a default signature, use the dropdown menu at the bottom of the window.
  7. Close the window when you are done. Changes save automatically.

One thing to note: Outlook for Mac does not support separate signatures for new messages and replies. You can only set one default signature per account.

Update Signature In Outlook On The Web (OWA)

Outlook on the web is the browser-based version. It is often used with Office 365 or Exchange accounts. Follow these steps:

  1. Log in to your Outlook web account at outlook.com or your company portal.
  2. Click the gear icon (Settings) in the top-right corner.
  3. At the bottom of the Settings panel, click View all Outlook settings.
  4. Go to Mail and then Compose and reply.
  5. Under Email signature, type or paste your new signature in the text box.
  6. Use the formatting toolbar to style your text. You can add links and images here too.
  7. Check the box to automatically include your signature on new messages.
  8. Click Save at the top of the page.

Your signature is now active. Remember that the web version has fewer formatting options than the desktop app.

How To Add An Image To Your Outlook Signature

Images make your signature stand out. You might want to add your company logo, a headshot, or a social media icon. Here is how to do it in each version:

Add Image In Outlook For Windows

  1. Open the signature editor as shown above.
  2. Click inside the edit box where you want the image.
  3. Click the picture icon in the formatting toolbar.
  4. Browse to your image file and select it.
  5. Resize the image by dragging its corners. Keep it small (under 100px wide is best).
  6. Click OK to save.

Tip: Use a PNG or JPG file. Large images may be blocked by email clients.

Add Image In Outlook For Mac

  1. Open the signature editor from Preferences.
  2. Click where you want the image.
  3. Go to the Insert menu and choose Picture.
  4. Select your file and click Open.
  5. Adjust the size as needed.
  6. Close the window to save.

Mac users often find that images appear smaller than expected. You may need to test by sending yourself an email.

Add Image In Outlook On The Web

  1. Open the signature editor in Settings.
  2. Click the image icon in the toolbar.
  3. Enter the URL of an online image, or upload a file from your computer.
  4. Resize using the handles.
  5. Save your changes.

Note: The web version does not support inline images as well as the desktop version. Test your signature before sending it to clients.

How To Add Hyperlinks To Your Outlook Signature

Links to your website, LinkedIn profile, or portfolio are common in signatures. Here is how to add them:

Add Links In Outlook For Windows

  1. Select the text you want to turn into a link.
  2. Click the link icon in the toolbar (looks like a chain link).
  3. Paste the URL in the Address field.
  4. Click OK.

You can also link an image. Just select the image before clicking the link icon.

Add Links In Outlook For Mac

  1. Highlight the text or image.
  2. Right-click and choose Hyperlink.
  3. Enter the URL and click OK.

Mac users sometimes report that links do not work in preview. They will work once the email is sent.

Add Links In Outlook On The Web

  1. Select the text.
  2. Click the link icon in the formatting toolbar.
  3. Paste the URL and click Insert.
  4. Save your signature.

Links in web signatures work fine, but they may not be clickable in the editor itself.

How To Create Multiple Signatures In Outlook

Many people need different signatures for different purposes. For example, a formal signature for clients and a casual one for colleagues. Here is how to manage multiple signatures:

Create Multiple Signatures In Outlook For Windows

  1. Open the signature editor from File > Options > Mail > Signatures.
  2. Click New and name your signature (e.g., “Client Signature”).
  3. Design the signature as you want.
  4. Repeat to create another signature.
  5. Under “Choose default signature,” select which account uses which signature for new messages and replies.

You can switch between signatures manually when composing an email. Just click the Signature button in the message window.

Create Multiple Signatures In Outlook For Mac

  1. Open Preferences > Signatures.
  2. Click the + button to add a new signature.
  3. Name it and design it.
  4. Use the dropdown to set a default for each account.

Mac does not allow separate signatures for replies. You will have to manually choose one each time.

Create Multiple Signatures In Outlook On The Web

  1. Go to Settings > Mail > Compose and reply.
  2. You can only have one signature per account in the web version.
  3. To switch, you must edit the existing signature or create a new one by deleting the old one.

This is a limitation of the web app. Consider using the desktop version if you need multiple signatures.

How To Set A Default Signature For New Messages And Replies

Setting a default signature saves you from manually inserting it every time. Here is how to configure it:

Set Default Signature In Outlook For Windows

  1. Open the signature editor.
  2. At the bottom, you will see two dropdown menus under “Choose default signature.”
  3. Select the signature for new messages.
  4. Select the signature for replies and forwards (often you want a shorter one here).
  5. Click OK.

You can choose “none” for replies if you do not want a signature there.

Set Default Signature In Outlook For Mac

  1. In the signature editor, select an account from the list.
  2. Use the dropdown at the bottom to choose the default signature.
  3. Close the window.

Mac only has one default per account, so it applies to both new messages and replies.

Set Default Signature In Outlook On The Web

  1. In the signature editor, check the box “Automatically include my signature on new messages I compose.”
  2. There is no separate option for replies. It uses the same signature.
  3. Save.

If you want no signature on replies, you will need to delete it manually each time.

Common Problems When Updating Your Outlook Signature

Sometimes things go wrong. Here are frequent issues and how to fix them:

  • Signature not showing up: Check that you have selected the correct default signature in the settings. Also, ensure you are not using a plain text format.
  • Image not displaying: Images must be hosted online or embedded. Outlook blocks external images by default. Use a small inline image.
  • Fonts look different: Use web-safe fonts like Arial, Calibri, or Times New Roman. Custom fonts may not render on all devices.
  • Signature appears twice: This happens if you have a signature set in both Outlook and your email server. Disable one.
  • Links not working: Make sure the URL is complete (including https://). Test by sending an email to yourself.

If you still have trouble, restart Outlook. Sometimes a fresh start clears glitches.

Tips For A Professional Email Signature

A good signature is clean and informative. Follow these guidelines:

  • Keep it short. Include your name, title, company, phone, and email.
  • Add one or two links, like your website and LinkedIn.
  • Use a small logo or headshot. Do not use large images.
  • Use a single font and consistent colors.
  • Include a legal disclaimer if required by your company.
  • Test your signature on mobile devices.

Avoid cluttering your signature with too many social media icons or quotes. Less is more.

How To Remove An Email Signature In Outlook

If you no longer need a signature, here is how to delete it:

Remove Signature In Outlook For Windows

  1. Open the signature editor.
  2. Select the signature from the list.
  3. Click the minus sign (Remove).
  4. Set the default to “none” if needed.
  5. Click OK.

  2. Select the signature and press the minus button.
  3. Close the window.

Remove Signature In Outlook On The Web

  1. Go to Settings > Mail > Compose and reply.
  2. Delete all text from the signature box.
  3. Uncheck the automatic inclusion box.
  4. Save.

Deleting a signature is permanent. Make sure you have a backup if needed.

How To Update Email Signature In Outlook For Multiple Accounts

If you manage several email accounts in Outlook, you can set different signatures for each. Here is how:

For Windows

  1. Open the signature editor.
  2. Under “Choose default signature,” select an email account from the first dropdown.
  3. Choose the signature for new messages and replies.
  4. Repeat for each account.

For Mac

  1. In the signature editor, you will see a list of accounts on the left.
  2. Select each account and assign a signature.

For Web

The web version only supports one signature per account. You must edit each account separately by switching accounts in the settings.

This is a common task for people with work and personal email in one Outlook profile.

Frequently Asked Questions

How Do I Update My Email Signature In Outlook Without Losing Formatting?

Use the built-in signature editor instead of copying from Word. The editor preserves formatting better. If you must copy, use the “Paste as plain text” option and then reformat.

You likely have a different signature set for replies. Go to the signature editor and set a signature for replies, or choose “none” if you do not want one.
