How to Create a Link in an Outlook Email Signature

To create a link in an Outlook signature, open the signature editor, select the words or image you want people to click, choose the link command, and enter the full web address. Save the signature, insert it into a new message, and test the link before relying on it. The exact route to the editor depends on whether you use classic Outlook, new Outlook, Outlook on the web, or Outlook for Mac.

What You’ll Need

An Outlook account and access to the signature editor in your version of Outlook.
The destination address, written in full. For a website, use a complete address such as https://www.example.com, rather than just a site name.
The text you want to display, such as Visit our website, or an image, such as a company logo. Using descriptive text is usually clearer than showing a long URL.
A few minutes to save and test the signature in a draft email. If your organization controls signatures centrally, you may need your Microsoft 365 administrator to make changes.

Step-by-Step

Open the signature settings for your Outlook version.
In classic Outlook for Windows, open File > Options > Mail > Signatures. In new Outlook for Windows, select the gear icon to open Settings, then go to Accounts > Signatures. In Outlook on the web, select the gear icon and open Accounts > Signatures. In Outlook for Mac, open Outlook > Settings > Signatures; some older Mac releases call Settings Preferences. If your interface has been updated, use Settings search to find Signatures.

These routes lead to different-looking editors, but the basic process is the same. If you have more than one email account, check which account’s signature you are editing before you make changes.
Create a signature or choose the one you want to edit.
If you are starting from scratch, choose the control to create or add a signature, give it a useful name, and type the signature content into the editor. If you already have one, select it from the list. A signature name is for your own reference; it is not the text recipients see. You might name versions Work, Personal, or Short reply to make them easy to identify.

Before editing an existing signature, consider copying its text somewhere safe. This is especially useful if the editor has complicated formatting, a table, or a logo. That way, you can restore the original if a change shifts the layout.
Add the text you want to turn into a link.
Type a short, meaningful label where you want the link to appear. For example, add Visit our website, Book an appointment, or View the product guide. You can also type an email address if you want recipients to be able to start a new message to that address.

Keep the wording specific enough that a recipient can tell what will open. A label such as Click here gives little context, especially when someone is reading quickly or using a screen reader. You can place the link on its own line or include it alongside other signature details, such as your phone number or job title.
Select the exact text to link.
Drag across the words in the signature editor so only the intended label is highlighted. If you select surrounding punctuation or a space, that character may become part of the clickable area. You can link a full web address too, but descriptive link text usually makes a signature cleaner and easier to scan.

To link an image, first add or select the image in the signature editor, then use the link command while the image is selected. The steps for selecting an image can differ between editors. If the editor will not let you select the image and link it, use a short text link below or beside it instead.
Insert the hyperlink and enter its destination.
Use the editor’s link or hyperlink button. In many Outlook editors, you can also select the text and press Ctrl+K on Windows. On a Mac, the equivalent shortcut is usually Command+K. In classic Outlook, the button appears in the signature editing area; in new Outlook and Outlook on the web, look for the link icon in the formatting toolbar. If a shortcut does not open the link dialog in your version, use the toolbar button.

In the dialog, enter the destination in the address field. For a website, include the protocol, for example https://www.example.com/contact. For an email link, use the email option if it is offered, or enter an address beginning with mailto:, such as mailto:help@example.com. Check the address carefully, then choose the control to insert or apply the link. The selected label should now appear as a hyperlink, often with colored or underlined text.
Review the appearance and save the signature.
Check that the link is attached to the intended words or image and that the surrounding signature still looks right. The link’s color and underline may be controlled by Outlook’s formatting or by the recipient’s email app, so do not rely on color alone to communicate that text is clickable. Make sure the label remains readable and does not blend into nearby details.

Save or confirm your changes using the button shown in the signature settings. In classic Outlook, close the signature dialog with OK, then close Outlook Options with OK to apply the change. In new Outlook or the web, use the save control if one is shown; some settings panes save changes automatically. Wait for any save indicator to finish before closing the pane.
Choose when Outlook should add the signature, if needed.
In classic Outlook, use the default signature options to choose an email account and assign the signature to new messages and replies or forwards. In new Outlook and Outlook on the web, look for the setting that automatically includes the signature on new messages and on replies or forwards. Select the relevant options and account. If you prefer to insert signatures manually, leave automatic insertion off and choose your signature from the message compose toolbar when writing an email.

Automatic insertion is convenient, but a long signature can take up space in a reply chain. You can create a shorter reply signature or insert the full one only when it is useful. Check the settings for each account if you send mail from more than one address.
Test the signature in a message.
Open a new message and confirm the intended signature appears. If it does not, insert it from the message’s signature menu or revisit the default settings. Click the link in the draft if Outlook allows it, or send a test message to an address you can access and open the link from the received message. Confirm that it opens the correct page or starts a message to the expected address.

Testing in a received message matters because the recipient’s email program may display formatting differently from the signature editor. If the link is correct but its appearance changes, focus on whether the label is readable and the destination works, rather than expecting every app to show identical colors or underlining.

Common Mistakes

Entering an incomplete web address: A site name without a full address may not be recognized as the intended destination. Enter the complete address, including https://, and check for missing letters, extra spaces, or punctuation accidentally included at the end.

Linking the wrong text: If you select the whole line, the whole line becomes clickable. If you select only part of a label, recipients may find the link unclear. Highlight the precise wording you want to link before opening the hyperlink dialog.

Forgetting to save or apply the change: Closing a settings pane too soon can leave the old signature in place. Look for a save control or confirmation, and reopen the editor to verify the updated version is still there.

Editing one signature but using another: Outlook can store multiple signatures, and different accounts may have different defaults. Confirm the selected signature name and account, then check which signature appears in a new message.

Assuming a link works because it looks blue: The visible formatting is not proof that the destination is correct. A hyperlink can point to an old or mistyped address. Open it from a test message and verify the destination itself.

Using an unclear label: A bare URL or generic phrase can be hard to interpret. Choose wording that tells the reader what to expect, such as See our opening hours or Download the setup guide. Do not promise that a page is secure or official unless you know that it is.

Tips

Use a short, descriptive link label. A compact phrase keeps the signature tidy and gives recipients context before they click. It also remains understandable if the email is read aloud by assistive technology.
Prefer secure web addresses. Use the site’s HTTPS address when available. If your organization provides a specific approved URL, use that exact link rather than guessing or using a third-party redirect.
Keep the signature simple. A link that matches the surrounding font and size is less likely to disrupt the layout. Avoid adding several competing links; include only destinations that recipients are likely to need.
Use an email link only when it helps. A mailto: link can start a new message, but it does not send one automatically. The recipient still needs to review and send the message, and their email app may ask which account to use.
Test on more than one device when the signature is important. Check a desktop email and a phone if possible. Mobile apps can wrap lines differently, and a logo or long label may appear in a different position than in the editor.
Keep a copy of complex formatting. Before changing a signature with a logo, table, or carefully arranged contact details, save a backup of its content. If the formatting becomes difficult to restore, you can recreate it from the copy.

Troubleshooting

The link command is unavailable or does nothing. Click inside the signature editor, select text or an image, and try the toolbar link button. Keyboard shortcuts can behave differently depending on the Outlook version and whether the editor has focus. If the editor is read-only, check that you chose an editable signature and that you have permission to change it.

The signature does not appear in a new message. Reopen the signature settings and check the default for the account you are using. Confirm that the signature is assigned to new messages, or insert it manually from the compose window’s signature menu. If you have multiple accounts, send the test message from the same account whose signature you edited.

The link is missing after saving. Return to the signature editor and inspect the selected signature. If the link is gone, select the label again, add the destination, and use the save or apply control. In Outlook on the web or new Outlook, allow the settings pane to finish saving before closing it. If changes repeatedly disappear, refresh Outlook and check whether your organization manages signatures centrally.

The link opens the wrong page or gives an error. Edit the link rather than only changing the visible label. Select the linked text, open the link editor, and inspect the destination field. Remove unwanted spaces and punctuation, confirm the full address, then save and test again. If the address is correct but the site still fails, try opening it in a browser and check with the website owner or your organization’s IT team.

The link works in the editor but not in a sent email. Send a test message to yourself and open the received version. Some security settings or email services may rewrite links, and a recipient’s organization may block certain destinations. If the message is in plain-text format, formatting and clickable behavior can differ. Try composing in HTML format, where available, and repeat the test; do not assume the recipient’s system will behave exactly like yours.

The signature layout changes after adding the link. Remove any unexpected font or color formatting from the linked text and match it to the surrounding signature. If a logo shifts, try placing a simple text link on a separate line instead of making the image clickable. If the signature is centrally applied by an employer, contact the administrator rather than repeatedly editing a local copy.

Frequently Asked Questions

Can I add a link to an existing Outlook signature?
Yes. Open the signature editor, choose the existing signature, select the text or image, add the hyperlink, and save. You do not need to rebuild the whole signature unless its formatting is damaged.

Can I make a company logo in my signature clickable?
Usually, yes. Select the logo in the signature editor and add the destination through the link command. Test it in a received message. If your Outlook editor does not allow linking the image, add a clear text link beside or below it.

Can a signature link open a new email?
Yes. Use an email hyperlink or a mailto: destination such as mailto:help@example.com. Clicking it generally opens a new message addressed to that recipient, but the result depends on the recipient’s device and default email app.

Why does my link look different to recipients?
Email apps can apply their own link colors, underlining, and font styles. That does not necessarily mean the link is broken. Use descriptive words that remain clear without color, then test the destination in a received message.

Can I use the same linked signature on Windows, Mac, and the web?
Outlook signatures and settings may be stored or synchronized differently depending on the account and Outlook version. Check each version you use and confirm the right signature appears for the correct account. If it does not synchronize, recreate or update it in that version.

How do I remove or change a signature link?
Open the signature editor, select the linked words or image, and use the link control to edit or remove the destination. If there is no remove option, you can remove the hyperlink formatting from the selected text and add a corrected link. Save the signature and test it again.
