An email signature is like a business card that accompanies every message you send. Yet, many people in Trois-Rivières and elsewhere in Quebec still send emails without a signature, or with a makeshift one that changes from one device to another. The result: less credibility, clients searching for your phone number, and an inconsistent brand image.
The good news is that setting up a signature in Outlook takes just a few minutes. Once in place, it's automatically added to the bottom of each message. Here's how to do it, step by step, in both the new version of Outlook and Outlook on the web, as well as the classic desktop version.
Quick answer: In the new version of Outlook or on the web, go to Settings, Mail, then Compose & Reply. In classic Outlook, go to File, Options, Mail, Signatures. Write your signature, check the box to automatically add it to new messages and replies, and then save.
1. Why a professional signature is worth the effort
A well-crafted signature works for you with every message. It reassures the recipient, gives your communications a polished look, and makes it easier for your customers to contact you. For an SME, it's a detail that speaks volumes about the company's professionalism.
A uniform signature offers several tangible benefits:
- Your contact details (phone, website, address) are always just a click away.
- Your logo and colours reinforce brand recognition.
- The entire team projects a consistent image, regardless of who is writing.
- You reduce the risk of error, because the information is no longer typed by hand each time.

2. Add a signature in the new version of Outlook and on the web
The new Outlook app for Windows and Outlook on the web share the same settings. The procedure is identical in both cases.
- Click on the gear icon (Settings) in the top right corner of the screen.
- From the menu, choose Mail, then Compose and Reply.
- Under the Electronic Signature section, give your signature a name (for example, "Pro").
- Write the text in the provided area: name, title, company, telephone, website.
- Further down, choose to apply this signature to new messages , replies, and forwards.
- Click Save. That's it.
You can create multiple signatures, for example, a full version for initial contacts and a shorter version for everyday exchanges. Outlook lets you change your signature directly in the message composition window.
3. Create a signature in Outlook classic (desktop)
If you are still using the classic version of Outlook installed on your computer, the path differs slightly, but remains simple.
- Open Outlook, then go to File, Options, Mail.
- Click on the Signatures.
- Tap New, name your signature, and then type its content in the large text box.
- On the right, under "Choose default signature", select your account, then associate the signature with new messages and replies.
- Confirm with OK.
A practical tip: if your team shares the same brand guidelines, have a template signature approved and then distribute it. This avoids homemade versions that all end up being different. Our technicians in the Mauricie region often deploy it automatically on all workstations within a company, guaranteeing a consistent look and feel without each employee having to recreate it.
4. What to include in a signature (and what to avoid)
A good signature is short and easy to read. The goal isn't to say everything, but to convey the essentials at a glance. Aim for four to six lines maximum.
Elements to include:
- Your full name and title.
- The company name and, if necessary, the logo.
- A direct phone number.
- The website address.
- A link to your services or a discreet call to action.
What you should avoid: endless quotes, a dozen social media icons, overly large images, or lengthy legal disclaimers that weigh down every message. If you manage multiple employees and want a consistent, company-wide look, our managed IT services allow you to deploy a standardized signature across your entire network in a single operation.

5. Add a logo, links, and clean formatting
To insert a logo, use the image icon in the signature editor, then select your file. Keep the image small, around 150 to 250 pixels wide, so it displays correctly without slowing down the message opening time. Ideally, host the logo on your website rather than pasting a large image, which reduces the email's file size.
To make your website or address clickable, highlight the text, then use the link tool (the chain icon). Avoid hard-to-read colored text and limit yourself to one or two fonts. A simple signature looks better on all devices, including phones, where a large portion of emails are read today.
6. Common mistakes and good safety reflexes
Some common pitfalls are common. Here they are, along with how to avoid them:
- Signature not appearing: check that it is associated with the correct account and activated for new messages.
- Broken image: A logo pasted from a local folder may not display correctly on the recipient's device. Use an image hosted online.
- Duplicate signatures: if two signatures are added, it is often because a rule or an add-on module inserts a second one.
From a security standpoint, be cautious about the information you share. A signature doesn't need your home address or sensitive details, as this data can be used for targeted phishing attempts. The Canadian Centre for Cyber Security also reminds users to limit the amount of personal information they share via email.

Frequently Asked Questions
Why isn't my Outlook signature displaying automatically?
Most often, the signature isn't associated with the correct account, or the automatic addition option isn't selected. Go back to your signature settings and confirm that it applies to new messages, replies, and forwards.
Can I have multiple signatures in Outlook?
Yes. Outlook lets you create as many signatures as you like, for example, a long version and a short version. You can choose a default and change it manually in the message composition window.
How do I add a signature on Outlook mobile?
In the Outlook mobile app, open the Settings menu, then Signature. The mobile version keeps its own signature, independent of the desktop version, so remember to configure it as well to maintain consistency.
