How to Add a Link to Your Outlook Signature (New, Classic, Mac)

You can add a link to your Outlook signature in about a minute. The hard part is that "Outlook" is several different programs, and each one hides the signature settings in a different place. Pick the wrong set of steps and nothing on your screen matches.

So this post starts with which Outlook you have, then gives the steps for each one, then covers the places where adding a link goes wrong. I checked every step against Microsoft's own help pages, and I say below where I had to lean on someone else's.

How to add a link to your Outlook signature: start with your version

Microsoft's signature page covers new Outlook for Windows, classic Outlook for Windows, Outlook on the web and Outlook.com, and sends Mac users to a separate page. Microsoft also says that if the new Outlook steps don't match what you see, you probably aren't using new Outlook yet, so try the classic ones.

A quick way to tell: if your signature settings are under Settings > Accounts > Signatures, you are in new Outlook or Outlook on the web. If they are under File > Options > Mail > Signatures or Message > Signature > Signatures, you are in classic Outlook.

Add a link in new Outlook and Outlook on the web

1. Select Settings, then Accounts > Signatures. This is the path Microsoft gives.
2. Open the signature you want to change, or add a new one.
3. Type the words you want people to click, such as "Watch a Demo", and select them.
4. Click the Insert link icon in the toolbar, or press Ctrl + K. Ablebits, which sells add-ins for Outlook, describes these steps. Microsoft's page says a signature can include links but does not walk through the click.
5. Paste the full address (starting with https://) into the web address box, and click OK.
6. Select Save.

Add a link in classic Outlook for Windows

1. Open a new email. On the Message tab, select Signature, then Signatures. This is Microsoft's path as well.
2. Under Select signature to edit, pick your signature.
3. In the Edit signature box, select the text you want to turn into a link.
4. Click the link button in the small formatting bar under Edit signature, enter the address in the Address box, and click OK. Microsoft says links are added with that bar, and its steps for linking icons in a signature use Insert > Hyperlink and the Address box.
5. Click OK to save.

To fix a link that is already there, right-click it and choose Edit Link or Edit Hyperlink, then change the Address or the Text to display.

Add a link in Outlook for Mac

Microsoft's Mac page gives these steps:

1. On the Outlook menu, select Settings.
2. Under Mail, select Signatures.
3. Pick your signature, or add a new one with the plus button.
4. In the signature editor, select See more items (...), then Link.
5. Type the Text to Display and the Address, and select OK.
6. Close the Signatures window.

One thing to know: the same page says support for legacy Outlook for Mac ends in October 2026. If your menus don't match these steps, you may be on the legacy version, and that page has a separate tab for it.

Linking a logo instead of text

Add the picture first, then link it. WiseStamp, a signature-generator company, says to insert the image, double-click it to select it, then click the link icon. Some people report that Outlook swaps the picture for a text link when they save. A Microsoft Q&A thread has one user's workaround, which is a space before the picture. That is a community tip, not Microsoft's advice.

My own view: put your name, title and the link you want clicked in text, and treat a logo as decoration. A text link survives when images are blocked, and classic Outlook blocks automatic picture downloads by default.

When the link won't save

The most common complaint I found is in Outlook on the web. In a Microsoft Q&A thread started in November 2024, a user says the link box opens but the cursor never reaches the address field, so typing overwrites the signature. A Microsoft community moderator replied that the Outlook team was aware and gave no date for a fix. Another user later posted a workaround that worked for them:

• Open a new email.
• Write the signature there and add the link in the message body.
• Copy the whole signature.
• Paste it into the signature box in Settings and save.

I don't know whether Microsoft has fixed this since. If your link box misbehaves, try the workaround before you spend an hour on it. The moderator also suggested switching back to classic Outlook for Windows, which "may not have this issue".

Test it before you rely on it

Send yourself an email and click the link. Then open it on your phone. Microsoft notes that signatures are stored on the device where you made them and may not be there in Outlook on another device, so check each place you send email from.

Which link should you add?

The easy choice is your homepage. I think it is the weakest one. EmailAnalytics makes the same point: a generic homepage link adds length without changing what the reader does. If your signature has room for one link, give the reader a next step.

I wrote about that choice in the best link for a SaaS email signature. Short version: "Book a demo" is for the buyer who is ready to talk. Put "Watch a Demo" beside it for the buyer who wants to look first.

Here is how that works with DemoSix. Capture Leads gives you a clickable link labelled "Watch a Demo". When a prospect clicks it, they enter their name and email, watch the demos you chose, and you see what they watched. They don't need an account.

Two details matter for Outlook:

• The words are yours to change. The label "Watch a Demo" is only the starting text. You can reword it in Outlook, and the address behind it stays the same. Use the edit steps above, and change the Text to display, not the Address.
• Plain-text signatures get the address. If your signature is plain text, DemoSix gives you the address itself to paste.

Capture Leads is on every plan, Basic included: one signature link and 50 new leads a month free, unlimited leads on Standard and Teams. The pricing page has the current plans.

The takeaway

Find out which Outlook you are in, then follow that one set of steps: select the words, add the link, save, and send yourself a test. Do the test every time. The thread above shows the link box can misbehave, and a quick test email costs you nothing.

And choose the link on purpose. A link to your homepage is a link. A link that gives a stranger a way to see your product, and tells you who looked, is a reason to have a signature at all.
