Outlook Signature: How to Create and Set It Up for Email

To create a signature message in Outlook, open the signature settings for your version, add your name and contact details, then choose whether Outlook should add it to new messages, replies, or both. You can also insert a saved signature manually while composing an email. Before you begin, decide what information belongs in your sign-off and which email account should use it.

What You’ll Need

Access to the Outlook account where you want to use the signature.
Your preferred sign-off details, such as your name, job title, phone number, website, or postal address. Include only details you are comfortable sharing with every recipient.
Optional: a logo or other image saved on your device, and the correct web address for any links you plan to add.

Step-by-Step

Open the signature settings for your Outlook version. In new Outlook for Windows, select the gear icon to open Settings, then go to Accounts > Signatures. In Outlook on the web, open Settings and look for Accounts > Signatures; if the settings layout differs, use the Settings search field and search for “signature.” In classic Outlook for Windows, go to File > Options > Mail > Signatures. On Outlook for Mac, choose Outlook > Settings > Signatures. Older Mac versions may label Settings as Preferences.
Create a new signature. In new Outlook or Outlook on the web, choose the option to add or create a signature. In classic Outlook for Windows, select New in the Signatures and Stationery window, enter a name for the signature, and select OK. On Mac, select the plus button in the Signatures window. Give it a descriptive name such as “Work” or “Personal.” This label is for you; it does not appear in messages.
Write the message you want recipients to see. Add your name and the most useful contact information. For example, you might use “Jordan Lee” on the first line, “Customer Support” on the second, and a work phone number on the third. Keep the wording concise and check spelling, phone numbers, and email addresses. Avoid adding information that is not relevant to the people you normally contact.
Format the signature carefully. Use the editor’s formatting controls to adjust font, size, bolding, or color if needed. A few readable lines usually work better than a large block of text. To add a web link, select the relevant text and use the link control if available, then confirm the destination address. If you paste content from Word or a website, check that the font and spacing have not changed unexpectedly.
Add a logo or image only if it helps. Use the image control in the signature editor, if available, to select a file. Keep the image modest in size and make sure the signature still makes sense if the recipient’s email program does not display images. A logo is not a substitute for writing your name or including essential contact details as text.
Choose when Outlook should insert the signature automatically. New Outlook and Outlook on the web provide default-signature options for new messages and for replies or forwards. Select your intended signature beside the relevant choices. In classic Outlook for Windows, use the Choose default signature area: select the email account, then choose a signature for New messages and, separately, for Replies/forwards. Outlook for Mac also has default-signature choices; select the account and choose what to use for new messages and replies. If you prefer to add it yourself each time, leave the automatic option blank.
Save the signature and close settings. In new Outlook or the web version, select Save if the settings page shows a Save button. Classic Outlook saves the signature when you confirm the Signatures and Stationery window with OK. In Mac Outlook, close the settings after making your changes; if prompted, confirm them. Do not assume the signature has been saved until the settings window closes or shows that the change is complete.
Test it in a new email. Start a new message for the account you configured. If you selected a default for new messages, check that the signature appears in the message body. Send a test to yourself or save a draft, then review the displayed formatting and any links. Also open a reply or forwarded message if you enabled a signature for those. The signature is inserted into the message body, so you can edit or remove it before sending.
Insert a signature manually when needed. If it is not set as a default, or you want a different sign-off for one message, start composing and use the signature command on the message toolbar or ribbon. In classic Outlook for Windows, choose Message > Signature and select the saved signature. In other versions, look for the signature option in the compose toolbar or its More options menu. Select the signature you want, then place the cursor where it should appear if Outlook has not inserted it at the intended point.

The precise labels can shift as Microsoft updates Outlook, and new Outlook, the web app, and classic Outlook do not have identical settings screens. The key distinction is that classic Outlook uses File > Options, while new Outlook and Outlook on the web use Settings. If you do not see the path described for your screen, search Outlook settings for “signature” rather than changing unrelated mail options.

Common Mistakes

Setting a default for the wrong account: If you use several mailboxes, check the account selected in the signature settings. A signature assigned to one account may not appear when you compose from another.
Configuring only new messages: Replies and forwards have a separate default in many Outlook versions. Choose that option intentionally; otherwise, replies may have no signature or may use a different one.
Expecting a signature to appear in messages already sent: A signature is added when you compose a message. It does not automatically update old mail or add itself to messages that are already open.
Making the signature too long or image-heavy: A large block can overwhelm a short email, and some recipients hide images. Keep essential contact information in selectable text.
Forgetting to check the result: A link can point to the wrong page, pasted text can carry odd formatting, and an image may appear too large. Preview a real draft before relying on the signature.

Tips

Make separate signatures for distinct roles or accounts, and give each one a name that makes it easy to choose from the signature menu.
Put the information recipients need most near the top. A name, role, and one useful contact method are often enough for routine work messages.
Use descriptive link text, such as “Company website,” instead of a long web address when the editor allows it. Confirm the link opens the intended destination.
Consider leaving a signature off short internal replies if your Outlook version lets you set a different reply default or insert signatures manually.
Check the signature on a phone as well as a computer. Narrow screens can wrap lines differently, and some mobile apps use their own signature setting.

Troubleshooting

The signature does not appear in a new message: Reopen signature settings and verify the default is assigned to the account you are sending from. Check the new-message default separately from the reply default. You can also insert the saved signature manually from the compose toolbar. If you have multiple accounts, confirm the From field is using the expected one.

The signature appears twice: This can happen if a signature is set to insert automatically and you also select it manually, or if text from an earlier reply already contains one. Remove the duplicate in the message body. Then decide whether to rely on automatic insertion or manual insertion for that type of message.

Formatting or images look wrong: Edit the signature and simplify the layout. Remove extra blank lines, resize a large image, or replace pasted content with plain text and format it again in Outlook. Send a new test message because an editor preview may not match how another email app displays the content.

The saved signature is missing on another device: Signature availability and synchronization can depend on the Outlook app, account, and version. Check the signature settings in the app where it is missing, and create or configure it there if necessary. Outlook for iOS and Android has a separate signature setting in the app’s Settings; signatures there may not match desktop settings. Send a test from that device before using it for important messages.

You cannot find the signature setting: Confirm whether you are using classic Outlook, new Outlook, Outlook on the web, or the mobile app. In desktop or web Outlook, use the Settings search box and search for “signature.” In classic Windows Outlook, the route is File > Options > Mail > Signatures. If the account is managed by an organization and settings are unavailable, ask your Microsoft 365 administrator whether a policy controls signatures.

Frequently Asked Questions

Is an Outlook signature the same as a signature message?
A signature is a saved block of text or other content that appears at the end of an email. It is not a digital certificate or a handwritten signature that verifies identity. You can set it to appear automatically or insert it into a message yourself.

Can I have more than one signature?
Yes. Create and name multiple signatures, such as Work and Personal, then choose a default for each account or select another saved signature while composing. Available default choices vary slightly by Outlook version.

Can I use different signatures for new emails and replies?
Yes, in Outlook versions that offer separate defaults. Choose one for new messages and another for replies or forwards, or leave one choice blank. If your version does not offer the distinction where you expect it, insert the signature manually in that type of message.

Why does my signature not show up on my phone?
Outlook mobile may use a separate signature from desktop or web Outlook. Open the Outlook app’s Settings, find the Signature option, and add or edit the mobile sign-off there. Send a test message from the phone to confirm the result.

Can I add a logo, links, or formatted text?
Usually, yes. Outlook’s signature editor supports text formatting and may provide controls for links and images. The exact controls differ by version. Keep important details as text and test the message in another email app, because recipients’ settings can affect image display and formatting.

How do I remove a signature from just one email?
Click in the message body, select the signature text or image, and delete it before sending. This changes that message only; it does not remove the saved signature or change its default setting.
