How to Create and Set Up an Email Signature in Outlook

To create an email signature in Outlook, open the signature settings for your version, make a new signature, add and format your contact details, then choose whether Outlook should insert it on new messages, replies, or both. The menu names differ slightly between classic Outlook for Windows, new Outlook, Outlook on the web, and Outlook for Mac, so use the steps below that match the app you have.

What You’ll Need

Access to the Outlook account where you want to use the signature. If you have several accounts, decide which ones need a signature.
The exact details you want to include, such as your name, job title, phone number, company, website, or a brief sign-off. Check spelling, phone numbers, and links before saving.
Optional: a small logo or other image file, if your workplace permits images in email signatures. For a work account, check your organization’s signature or branding policy first.
A few minutes to send yourself a test message and check how the signature appears on a phone or another email service.

Step-by-Step

Identify which Outlook you are using. Classic Outlook for Windows has the traditional File tab and desktop ribbon. New Outlook for Windows has a simplified interface and a Settings gear. Outlook on the web runs in a browser. On a Mac, use the Outlook app’s settings. If you are unsure, check whether the app has a File tab: if it does, follow the classic Windows steps; if not, look for the Settings gear.
Open the signature settings.
- New Outlook for Windows or Outlook on the web: select the Settings gear, then go to Accounts > Signatures. In some web layouts, or where the interface has not yet changed, the path may appear as Mail > Compose and reply. If you do not see Accounts, search Outlook settings for “signature.”
- Classic Outlook for Windows: select File > Options > Mail > Signatures.
- Outlook for Mac: from the menu bar, select Outlook > Settings > Signatures. In some older releases, Settings may be called Preferences.
Create a named signature. In the signature window, choose the option to add or create a signature. Type a name that will help you identify it, such as “Work” or “Personal,” and confirm. The name is for your reference; it is not necessarily the text recipients will see. If you use separate signatures for different roles or accounts, create one at a time and give each a clear name.
Enter the signature text. Click or tap in the editing box and type the information you want to appear at the end of your email. A practical work example might be your full name on the first line, your role and organization on the second, and a work phone number or website on the next line. Keep it concise and use details that are appropriate for the account. Avoid adding private information to a signature that may be used for business correspondence.
Format it for easy reading. Select text to change its font, size, color, or emphasis using the formatting controls available in your version. Use a readable font and modest styling; a signature should be clear even when viewed on a small screen. You can add a hyperlink by selecting the relevant text and using the link control, then checking that the destination is correct. For example, link the words “Company website” instead of pasting a long web address into the signature.
Add an image only if you need one. Use the picture or image button in the editor to insert a logo file if that control is available. Choose a small, clear image and keep important contact information as selectable text rather than placing all of it inside a graphic. Large images can make messages slower to load, and some recipients’ email programs may block images until the reader allows them. If your organization provides a logo, use its approved version rather than a screenshot or a stretched image.
Set the automatic signature options. In new Outlook and Outlook on the web, choose the signature for New messages and, separately, for Replies and forwards, if those selectors are shown. In classic Outlook for Windows, use the Choose default signature area to select an email account, then choose the signature for new messages and for replies/forwards. In Outlook for Mac, use the default-signature controls in the signature settings if available. Select “None” or leave a setting unassigned if you want to insert a signature manually for that type of message. Make sure you are assigning it to the intended account.
Save, close settings, and test it. Some versions save changes as you make them; others show a Save button. Use it if shown, then close settings. Start a new message and check whether the signature appears. If you assigned a signature to replies, reply to a message as a separate check. Review spacing, line breaks, links, and any image. Send a test email to an account you can open on a phone or in another mail service to see whether the layout holds up outside your Outlook view.

If you want to use more than one signature, create each one separately and choose the appropriate one from the message compose window when needed. An automatic default is convenient, but you can usually remove or replace the inserted text in a particular message before sending it.

Common Mistakes

Creating a signature but not assigning it. Saving text in the signature editor does not always make it appear automatically. Check the defaults for new messages and replies, and confirm the correct account is selected.
Editing the wrong account’s signature. Outlook can contain multiple mail accounts, and a default may be set separately for each. Verify the account name in the signature settings and test by composing from that account.
Making the signature too long. Several slogans, legal notices, social links, phone numbers, and images can overwhelm the message. Include only information readers need and follow any workplace rules for required notices.
Using formatting that does not travel well. Unusual fonts, complicated tables, and oversized graphics may look different in other email apps. Prefer simple text, restrained formatting, and a test message viewed in another client.
Assuming a signature syncs everywhere. Signature settings can behave differently across Outlook apps, accounts, and devices. If a signature is missing on your phone or another computer, check that app’s signature settings rather than assuming the desktop setting has been copied over.
Forgetting to check links and image privacy. A link can look correct but point to the wrong address. Images may be hosted online or included in a message in different ways; use only approved assets and avoid exposing private file locations.

Tips

Make the first line do the important work. Put your name and role where they are easy to spot. A recipient should understand who wrote the email without scanning a block of promotional text.
Use plain text details where possible. Text phone numbers and email addresses are easier to copy, search, and read with assistive technology than details embedded in a logo image.
Keep a personal and a work version separate. A short personal signature can avoid sharing business contact details from a personal account, while a work signature can follow your organization’s approved format.
Check how replies look. If the full signature appears after every short reply, a long conversation can become cluttered. You may prefer to use a shorter signature for replies or turn off automatic insertion there.
Use a neutral sign-off. A name and contact details are often enough. If you add a sign-off such as “Best,” make sure it does not duplicate text you routinely type before the signature.
Review the signature occasionally. Update it when your job title, phone number, website, or company branding changes. Send a fresh test message after a change, especially if you edited an image or link.

Troubleshooting

The signature does not appear in a new message. Return to signature settings and check that a default is selected for new messages and for the account you are composing from. In classic Outlook, revisit File > Options > Mail > Signatures and inspect the account and default selectors. In new Outlook or the web app, open the Settings gear and check Accounts > Signatures (or the available Mail signature settings). You can also insert the signature manually from the compose window’s signature option, if shown.

It appears in new mail but not in replies. Replies and forwards have a separate default in many Outlook versions. Choose the signature for that setting, save if required, and test by replying to a message. If you intentionally left it blank, use the compose window’s signature control when you want to add one.

The signature appears on the wrong account or is duplicated. Check which account is selected in the message’s From field and match it to the account’s signature default. If your signature text already includes a sign-off, remove any extra typed sign-off in the message. Also check whether a company-managed system or another device is adding a second signature.

Formatting or a logo looks wrong. Reopen the editor and simplify the layout. Try reducing image dimensions, removing unusual fonts, and using short lines of text. Send another test message to an external account. If a logo is missing only for recipients, their email app may be blocking external images; keep essential information in text so it remains available.

You cannot find the settings or your changes do not stick. Use the settings search box for “signature,” if available, and check that you are signed in to the intended account. Confirm changes with Save if the page offers that button. If settings are controlled by your workplace, or the controls are unavailable, contact your email administrator. As a temporary workaround, keep a copy of your signature text and paste it into messages until the setting is available.

Frequently Asked Questions

Can I have more than one signature in Outlook?
Yes. Create separate named signatures, such as “Work” and “Personal.” Set a default for common messages and choose a different signature from the compose window when you need it.

How do I add a signature to replies but not new emails?
In signature settings, set the new-message default to None or leave it unassigned, then select your signature for replies and forwards. The exact control depends on your Outlook version and account.

Can I create a signature in Outlook on the web?
Yes. Open the Settings gear and look for Accounts > Signatures; some layouts use Mail > Compose and reply. Add the text, set the defaults you want, and save if prompted.

Will my Outlook signature appear on my phone?
Not necessarily. Outlook mobile can have separate signature settings from desktop Outlook and the web app. Open Outlook on your phone, go to its settings, and check the signature setting for the account you use.

Can I include a logo or a social media link?
Usually, yes. Use the image and hyperlink controls in the signature editor where available. Keep images modest in size, check that links go to the intended pages, and follow your organization’s rules for logos and social links.

Why does my signature look different to the recipient?
Email apps do not always display fonts, spacing, and images in the same way. Use simple formatting, keep essential details as text, and send a test message to another email service to catch layout problems.
