Outlook Written Signature: How to Create and Set It Up

To create a written signature in Outlook, type the name and contact details you want at the bottom of your emails, save them in Outlook’s signature settings, and choose whether they should be added to new messages or replies. You can set this up in classic Outlook, the new Outlook for Windows, Outlook for Mac, or Outlook on the web. The steps vary slightly by version, but you do not need to draw or upload an image to make a text signature.

A written email signature is a short sign-off that can include your name, role, phone number, and other useful details. It is separate from the handwritten or digital signatures used to sign documents, and it does not by itself verify your identity or make an email legally signed.

What You’ll Need

Access to the Outlook account where you want the signature to appear.
The text you want to include, such as your name, job title, phone number, and website. Check spellings and contact details before saving.
A few minutes to set the signature and decide whether it should appear automatically on new messages, replies, or both.

Step-by-Step

Identify which Outlook version you are using. The labels differ, so first check whether you use classic Outlook for Windows, the new Outlook for Windows, Outlook for Mac, or Outlook in a browser. In classic Outlook, the File tab and the full desktop ribbon are visible. The new Outlook has a Settings gear near the top-right and a more web-like layout. Outlook on the web runs in a browser. If you are unsure, open the app’s Settings or Help area and look for its product name.
Open the signature settings. In classic Outlook for Windows, select File > Options > Mail > Signatures. In the new Outlook for Windows, select the Settings gear, then Accounts > Signatures. In Outlook on the web, select the Settings gear, choose Mail > Compose and reply, and find the email signature section. In Outlook for Mac, open Outlook > Settings > Signatures; some older Mac versions label Settings as Preferences. If a work or school account is managed by your organization, some options may be restricted.
Create a new signature. In classic Outlook, select New, enter a name that helps you recognize the signature, such as Work or Personal, and confirm. In the new Outlook or Outlook on the web, choose the option to add or create a signature and give it a clear name if prompted. In Outlook for Mac, use the plus button in the signatures list. The signature name is for your own reference; recipients see the text you put in the signature editor, not that label.
Type the signature text. Click in the editor and enter the information you want recipients to see. For example, you could type your full name on the first line, your role and organization on the second, then your phone number or website on another line. Use the Enter key to create line breaks. Keep the text concise and include only details appropriate for the messages you send. A plain-text signature is a good starting point because it is easy to read and less likely to display differently across email apps.
Format and review it. Select text to adjust the font, size, or emphasis using the controls available in the editor. A restrained format—readable font, modest size, and limited bolding—works well on phones and desktop screens. If you add a web address, make sure it is complete and correct. Read the signature from top to bottom and remove extra blank lines, accidental spaces, or repeated contact information. If the editor has no formatting controls, keep the signature in simple text rather than pasting in complex formatting from another app.
Choose when Outlook should add it automatically. In classic Outlook, use the Choose default signature area to select the email account, then choose a signature for New messages and, if wanted, for Replies/forwards. In the new Outlook or Outlook on the web, use the options below the editor to set the signature for new messages and replies or forwards. Outlook for Mac also lets you select defaults for an account and for new messages or replies. You can leave a default blank if you prefer to add the signature manually. These settings may be separate for each email account, so check the account shown in the settings.
Save the signature and test it in a message. Select Save or OK, depending on your version. Start a new email to confirm the signature appears where expected. Then create a reply or forward and check that setting too. If you chose not to insert it automatically, use the message window’s Insert > Signature option in the new Outlook or web version, or the Message > Signature command in classic Outlook. The Mac compose window also provides a Signature option when signatures are available. Send a test to yourself if you want to check how the finished message looks in an inbox.

When you send from another device, remember that signatures are not always synchronized in the same way as other account settings. A signature created in the desktop app may not automatically appear in Outlook on the web or on a phone. If you use several versions of Outlook, check each one and create or select a signature there when needed.

Common Mistakes

Setting a signature for the wrong account: Outlook can have several mailboxes, each with its own default settings. If the signature is missing or the wrong one appears, reopen the signature settings and confirm the selected account before changing the defaults.

Assuming the signature is added to every kind of message: New messages and replies or forwards often have separate controls. A signature may appear on a new email but not on a reply if you left that default blank. Check both settings and test each type.

Adding too much information: Long quotations, multiple phone numbers, social links, and decorative slogans can make the signature harder to scan, especially on a phone. Include the details recipients are likely to need for the purpose of the account.

Using repeated blank lines or pasted formatting: Text copied from Word or a website can bring in odd fonts, spacing, or invisible formatting. If the signature looks inconsistent, remove the content and type it directly in Outlook, then apply simple formatting in the editor.

Confusing an email sign-off with a document signature: A typed name at the end of an email is ordinary text. It is not a certificate-based digital signature, a handwritten mark, or proof that a document has been authenticated.

Tips

Make the first line easy to identify. Put your name first so people can quickly see who sent the message. Add a role or organization only if it helps the recipient understand the context.
Use a practical length. A few lines are usually easier to read than a large block. Consider whether each phone number, address, link, or tagline is useful to the people receiving your emails.
Keep a simple version for replies. Some people use a full signature on new messages and a shorter name or contact line on replies. If your Outlook version lets you choose different defaults, create two signatures and assign them separately.
Check links and spelling after editing. Open any website link from a draft to make sure it points to the intended page. Verify your name, title, and phone number before using the signature broadly.
Review the result on a small screen. A compact signature is less likely to wrap awkwardly on a phone. Send yourself a sample and view it in a mobile mail app as well as on a computer.
Do not include information you would not share widely. Email can be forwarded, so avoid adding personal details that recipients do not need. For work accounts, follow your organization’s branding and privacy policies.

Troubleshooting

The signature does not appear in a new email: Return to the signature settings, select the correct account, and check the default for new messages. Save the change, close the draft, and open a fresh message; a draft that was already open may not pick up a newly saved default. If you have chosen manual insertion, use the signature command in the compose window instead.

It appears on new messages but not replies: Set a default for replies and forwards as well, or insert the signature manually in the reply. Some people intentionally leave this setting blank to avoid repeating a long block in every message.

The wrong signature is inserted: Check which signature is assigned to the current account and message type. If you have multiple signatures, use the signature menu in the draft to select the correct one. Also confirm that Outlook is sending from the account whose settings you edited.

Formatting changes after sending: Recipients’ email programs can render fonts and spacing differently. Simplify the layout, remove pasted styling, and avoid relying on columns or elaborate spacing. Send a test to another account or device to see whether the issue is specific to one mail app.

Settings or buttons are missing: Make sure you are looking at the correct Outlook version and settings path. An administrator may manage signatures for a work or school account, or the account may be configured in a way that limits some features. Check Outlook updates and, for a managed account, ask your organization’s IT support whether signature settings are controlled centrally.

A signature created on one device is absent on another: Do not assume that signatures sync across all Outlook apps. Open signature settings separately in the other app or browser and create or choose the signature there. If your organization deploys a standard signature, contact its support team before making duplicate changes.

Frequently Asked Questions

Can I create a written signature without an image?
Yes. Type your name and any relevant contact details directly into the signature editor. An image is optional and is not needed for a standard text email signature.

How do I add my signature to just one email?
Leave the automatic default blank, then choose the signature command in the message compose window and select the one you want. The command is commonly under Insert in the new Outlook and web versions, or Message in classic Outlook.

Can I use different signatures for work and personal email?
Yes. Create separate signatures and assign the appropriate one to each account in signature settings. When composing, check the From account as well as the selected signature.

Why does my signature show up twice?
This can happen if Outlook inserts a signature automatically and you also insert it manually, or if a reply includes text from an earlier message. Remove the extra block from the draft and check that you have not added the same signature twice in your settings.

Will my Outlook signature appear on my phone?
Not necessarily. Mobile Outlook may have its own signature setting, and signatures made in desktop Outlook or the web may not carry over. Open Outlook on your phone, go to its settings, and check the signature for that app.

Does a typed email signature count as a digital signature?
No. It is text at the end of an email and does not provide cryptographic verification. If you need to digitally sign a message or sign a document, use the relevant secure signing feature or service rather than relying on a typed name.
