Outlook Email Signature: How to Create a New Signature

To create a new email signature in Outlook, open the signature settings for your version of Outlook, choose the option to add a signature, write and format it, then save it and select when Outlook should insert it. You can make separate signatures for new messages and replies. Before you start, decide what contact details you want to include; the steps differ slightly between new Outlook, classic Outlook for Windows, Outlook on the web, and Outlook for Mac.

An Outlook email signature is reusable text or formatted content added to the end of a message. It is not a digital certificate or a drawn handwritten signature. The instructions below cover the reusable email signature feature.

What You’ll Need

An Outlook account and access to the mailbox where you want the signature to appear.
The wording and contact information you plan to include, such as your name, role, phone number, or website. Check spelling and details before saving.
If you want a logo or other image, have a suitably sized image file ready. A simple text signature is usually easier to read on phones and when images are blocked.

Step-by-Step

Identify which Outlook you are using. The current Windows app is called new Outlook; classic Outlook is the desktop program with the File tab. Outlook on the web runs in a browser, and Outlook for Mac has its own settings. If you are unsure on Windows, look for a File tab: its presence usually means you are in classic Outlook. The settings path depends on this choice.
Open signature settings in new Outlook for Windows. Select the gear icon in the upper-right corner to open Settings. Go to Accounts > Signatures. If you have more than one account, check which account is selected or assigned to the signature; a signature may be available for one mailbox but not another. If the page layout differs, use the Settings search field and search for “signature.”
Open signature settings in classic Outlook for Windows. Select File > Options > Mail > Signatures. The Signatures and Stationery window opens. If you use multiple email accounts, note the account selector in the upper-right area of this window. Classic Outlook keeps its signature settings within the Outlook profile, so do not assume a signature created there will automatically appear in every Outlook app or on every device.
Open signature settings on the web or Mac. In Outlook on the web, select the gear icon and open Accounts > Signatures. Some organization or Outlook.com layouts may instead show the signature setting under Mail > Compose and reply; use Settings search if you cannot find it. In Outlook for Mac, open the Outlook menu and choose Settings (called Preferences in some older releases), then select Signatures. The controls can vary a little by app version.
Add a new signature. Select the add or plus button. In classic Outlook for Windows, choose New, enter a name for the signature, and select OK. In the other versions, use the new-signature control and provide a name if prompted. Choose a label that will be easy to recognize, such as “Work,” “Personal,” or “Short reply.” The label helps you choose the right signature; it is not normally displayed in the email.
Enter the signature content. Click in the editing box and type the information you want recipients to see. A clear basic example is your name on the first line, your role or organization on the next line, and one or two useful contact methods below. Keep the details current and avoid adding private information you would not want shared with every recipient. Use the editor’s formatting controls to apply a readable font, restrained color, or bolding.
Add a link or logo only if it helps. Select the words you want to link, such as your company name or website address, and use the editor’s link control to add the destination. To add a logo, use the picture or insert-image control if it is available in your version. Keep the image small enough not to dominate the message, and do not rely on it to communicate essential contact information. If the editor does not accept the image, save the text signature first and check your version’s image-insertion options rather than pasting a large image from an unrelated document.
Set when Outlook should use it, then save. Choose the email account to associate with the signature. Set it as the default for new messages if you want it added automatically. Set a separate default for replies and forwards if you want one there; a shorter version can keep long conversations tidy. On the web, enable the options to include the signature automatically on new messages and, separately, on replies or forwards. In classic Outlook, use the New messages and Replies/forwards menus. Select Save or OK as shown by your app.
Test it in a message. Start a new email for the correct account and confirm the signature appears where expected. Then test a reply if you enabled a reply default. Check the line breaks, links, image, and contact details. If it does not appear automatically, use the message’s Insert > Signature command (or the equivalent Signature control) to add it manually, then return to settings to check the default assignment.

Common Mistakes

Editing the wrong mailbox. A person can have several accounts open in Outlook. Check the selected account in signature settings and the From account on a test message. A signature set for one mailbox may not be the default for another.
Creating a signature but not setting a default. Saving a signature does not always mean Outlook will automatically add it. Select the new-message and, if wanted, reply/forward defaults. You can still insert a saved signature manually from the message toolbar.
Using a complex layout. Tables, multiple fonts, large logos, and decorative symbols can shift or look different in another email app or on a phone. Keep the layout simple and test a message sent to an account you can view outside Outlook.
Forgetting that replies need a separate choice. The setting for new messages may not control replies and forwards. Choose that option separately, or leave it blank if you prefer to insert a short signature only when needed.
Assuming every Outlook version shares the same signature. Settings created in classic Outlook may not be available in new Outlook, the web app, or Outlook for Mac. Confirm the signature in each app and account you use.

Tips

Make the first line your name so recipients can identify you quickly. Include only the contact channels you actually monitor.
Create a long signature for first-contact messages and a compact one for replies. Use distinct names in the signature manager so you can tell them apart when inserting one manually.
Use ordinary text for phone numbers, job titles, and essential details. Some recipients block images, and plain text is more dependable for accessibility and copying information.
Send yourself a test message and view it in a browser or on a phone if possible. A signature can look different in the composer and in the delivered email.
Review your signature when your role, phone number, website, or company branding changes. If you send from a shared mailbox, make a separate test from that mailbox rather than assuming your personal signature will be used.

Troubleshooting

The signature does not appear automatically: Reopen signature settings and check that the signature is assigned to the correct account and message type. New messages and replies can have separate defaults. Start a fresh message after saving; a message that was already open may not update its signature automatically. As a temporary fix, insert it from the message’s Signature menu.

The signature appears in the wrong account or is duplicated: Check the From field before sending and review defaults for each account. If the signature is already present in a reply, Outlook may add another one when you reply again. Remove the extra copy from the message and adjust the reply/forward setting or shorten the existing thread signature.

The logo is missing or looks too large: Some recipients’ mail programs block images by default, so keep key information as text. Reinsert the image using Outlook’s signature editor, resize it there if available, and send a test. If it appears as an attachment instead of in the signature, remove it and try the image-insertion control rather than dragging the file into the message.

You cannot find the signature settings: Confirm whether you are in new Outlook, classic Outlook, a browser, or Outlook for Mac, then follow the matching path above. Use Settings search for “signature” where available. In a work or school account, your organization may manage some settings; contact its IT support if the option is missing or changes do not save.

Your signature is not available on another device: First check that the other device is signed in to the same mailbox and app version. Signatures do not necessarily transfer between classic Outlook and other Outlook apps. Create or configure the signature in the app where it is missing, and check its default settings separately.

Frequently Asked Questions

Can I have more than one signature in Outlook?
Yes. Create and name separate signatures for different roles, accounts, or message types. You can select a saved signature from the message’s Signature menu when composing.

Can I use one signature for new messages and another for replies?
Yes. In signature settings, choose a default for new messages and a separate default for replies and forwards. You can leave either choice blank if you do not want Outlook to insert a signature automatically for that type.

How do I add a signature to one email without making it the default?
Open the email and choose the Signature control on the message ribbon or toolbar, then select the signature you want. The exact location varies by Outlook version. This inserts the saved signature into that message without changing the default.

Why does my signature show up twice?
A signature may already be in the reply text while Outlook also inserts the reply default. Delete the duplicate in the message and check the Replies/forwards setting. If the conversation contains older signature text, Outlook generally does not remove it for you.

Will my Outlook signature include a handwritten or legally binding signature?
No. The email signature feature adds reusable content such as text, links, and images; it does not authenticate a sender or create a digital signature. Use an approved signing service or certificate when a document requires a verified signature.

Does a signature sync between Outlook on my computer and the web?
Not in every setup. Availability depends on the Outlook app, account, and version. Check the signature settings in each app where you send mail, and create or select the signature there if it is missing.
