How to Create an Email Signature in Outlook on the Web

To create an email signature in Outlook on the web, open Settings (the gear icon), go to Accounts > Signatures, create and format a signature, then save it. Choose whether Outlook should add it automatically to new messages and to replies or forwards; in some accounts, the same settings are under Mail > Compose and reply.

Where Outlook on the web keeps signature settings

Outlook on the web is the browser version of Outlook, accessed through Outlook.com or an organization’s Microsoft 365 account. Microsoft has updated its settings layout over time, and the menu names can differ between accounts. In the newer layout, open the gear icon at the top of the page and select Accounts, then Signatures. In another layout, open Settings, choose Mail, and select Compose and reply. If you do not see either path immediately, use the Settings search box and search for signature.

Make sure you are signed in to the account whose outgoing messages should use the signature. A personal Outlook.com mailbox and a work or school Microsoft 365 mailbox can have separate signature settings, even when you open both in the same browser. If your organization manages Outlook settings centrally, some options may also be limited by its administrator.

Create and save a signature step by step

Sign in to Outlook on the web and select the Settings gear.
Open Accounts > Signatures, or Mail > Compose and reply if that is the route shown in your settings.
Select the option to create a new signature. Enter a name that will help you identify it, such as Work, Personal, or Support.
Type the signature into the editing area. Add your name and relevant contact or role details, then use the available formatting controls if needed.
Choose whether to use this signature automatically for new messages, replies and forwards, or both. These defaults can usually be set separately.
Select Save before leaving the settings page.

The signature name is for your own reference; recipients see the signature text, not the label you assigned it. If you create more than one, names such as Sales and Internal make it easier to select the right one while composing. After saving, open a new message to confirm the result. Settings changes do not necessarily update a message that was already open or drafted, so close and reopen the draft if the new signature does not appear.

Choose when Outlook inserts it

Automatic insertion is a convenience, not a requirement. Selecting the new-message default puts the signature at the end of messages you start. Selecting the replies-and-forwards default adds it to responses as well. If you leave a default unchecked, you can still insert the signature manually in a message using the signature control in the compose toolbar, then choosing the signature you want.

Consider how often you send short replies before enabling a signature on every response. A full name, title, phone number, and several links can make a brief exchange much longer, especially after a conversation has accumulated a number of quoted messages. Some people use a shorter reply signature or omit it on replies, while keeping a more complete signature for new emails. If your organization requires a particular disclaimer, follow its policy rather than removing or changing it.

When a signature appears in the wrong place, check the message body before sending. Outlook generally inserts it at the cursor or at the end of the message area, but replies can contain quoted text, separators, and previous signatures. A quick review helps prevent your new sign-off from landing below a long quoted thread where recipients may miss it.

What to include and how to format it

A useful signature gives the recipient enough information to identify you and follow up without turning the email into a brochure. For a typical professional account, start with your name and role, then add only the contact details that help people reach you. A simple example might be:

Jordan Lee
Project Coordinator | Northside Design
jordan.lee@example.com
555-0100
northsidedesign.example

Use the formatting toolbar in the signature editor to apply basic choices such as bold text, links, or lists when those controls are available. Keep the design readable in plain text and on a narrow screen. A restrained font treatment, one accent color, and a clear line break between your name and contact details are usually easier to scan than several font styles, decorative symbols, or a large block of centered text. The recipient’s email app may display fonts and colors differently from Outlook.

To add a link, select the relevant text and use the link control if available, then check that the destination is correct. Descriptive link text such as Company website is clearer than a long web address or a vague label such as click here. Do not include sensitive information that does not belong in routine correspondence, such as account credentials, private identifiers, or personal contact details you do not want shared.

Adding a logo or image safely

Outlook’s signature editor may allow you to insert an image, depending on the account and interface. If you use a company logo, keep it modest in size, use an approved file, and check the result in a test message. Large images can dominate a message, increase its size, or display awkwardly on mobile devices. Some recipients’ email clients block remote images until the recipient chooses to download them, so the signature should still make sense if the logo is not shown.

Do not make essential contact details part of a single image. A recipient may be unable to read or copy the information, and assistive technologies may not communicate it as clearly as ordinary text. Keep your name, phone number, and important links as selectable text; treat a logo as decoration or a supplementary link. If the editor does not offer a reliable way to insert the image, ask your organization for its approved instructions rather than pasting complex web code into the signature box.

Outlook on the web versus desktop Outlook

A signature created in Outlook on the web is configured for the mailbox and web experience you are using. Do not assume it will match signatures created separately in classic Outlook for Windows, Outlook for Mac, or another mail app. The exact behavior can depend on the Outlook version, account type, and how the app is configured. If you switch between the browser and desktop, send a test message from each one and compare what recipients will see.

In classic Outlook for Microsoft 365 on Windows, signatures are managed through File > Options > Mail > Signatures. Outlook for Mac has its own signature settings in the app’s settings or preferences, with labels that can vary by release. Those desktop paths are not the steps for editing a web signature. If the same account sends different sign-offs from different apps, check the signature settings in each app rather than repeatedly changing the web version.

Also distinguish Outlook on the web from the new Outlook for Windows. They share a modern design, but they are separate ways of accessing mail and may present settings differently. If you cannot find a menu item in the browser, verify that you are actually in a browser tab at Outlook.com or your organization’s Outlook web address, rather than in a desktop application.

Common problems and practical fixes

The signature does not appear automatically: Return to the signature settings and check the defaults for new messages and replies or forwards. Save the settings, then start a fresh message to test.
The signature appears twice: Check whether it is set as an automatic default and also being inserted manually, or whether a second mail app adds its own signature. Remove the duplicate in the draft before sending, then adjust the relevant setting.
Formatting changes after sending: Keep the layout simple and test it by sending a message to an account you can view in another mail client. Complex spacing, unusual fonts, and large graphics are more likely to look different across email apps.
A logo is missing: The recipient may have image downloading turned off, or the image may not have been added in a way that travels with the message. Keep important information as text and ask the recipient to check whether images are blocked.
The signature is missing from an existing draft: Create a new message or close and reopen the draft. A settings change may not refresh an editor that was already open.
The setting is unavailable: Confirm the mailbox at the top of Outlook, try the alternate settings path, and check whether your organization restricts signature features.

Before sending a message with a changed signature to a customer or a large mailing list, send a test to yourself. Check it on a computer and a phone if possible, and confirm that links work, line breaks are sensible, and the signature is not repeated beneath quoted text.

Frequently Asked Questions

Can I have more than one signature in Outlook on the web?

You can create multiple named signatures when the signature settings offer the create-new option. Give each one a clear name, set the automatic default you want, and choose another signature manually from the compose toolbar when a particular message needs different contact details.

How do I add a signature only to new emails?

In signature settings, enable the automatic option for new messages and leave the option for replies and forwards off. Save the change and open a new message to verify it. You can still insert a signature manually in a reply when it is appropriate.

Can I use an image as my entire signature?

You can sometimes insert an image, but relying on an image for all signature information is not a good choice. Images may be blocked or difficult to read and copy. Keep names, contact details, and important links as text, and use a logo only as an additional element.

Why is my Outlook signature different on my computer?

The browser, classic Outlook, new Outlook, and Outlook for Mac may have separate signature settings or handle them differently. Check the signature configuration in the app you used to send the message. A change made in Outlook on the web should not be treated as proof that every mail app has the same signature.

Does the recipient see the name I gave my signature?

No. The signature name is a label for choosing and managing signatures in your settings. The recipient sees the text and formatting you placed in the signature itself.

Review before you rely on it

Once your signature is saved, check it in a fresh message and send yourself a test. Confirm the automatic settings, spelling, phone number, links, and appearance on a small screen. Outlook’s menus can change and work or school accounts may have organization-specific controls, but the basic process is consistent: open the mailbox’s signature settings, create the content, choose when it is inserted, and save. A short, readable signature is generally more dependable than a heavily designed one, and checking it from the apps you actually use helps avoid surprises.
