Create or change your email signature

Signatures are saved separately in each version of Outlook. If you use Outlook on the web and the Outlook app on your computer, check both.

> If your company uses a central signature tool, your signature may be added automatically after you send. In that case, don't add your own, or you'll get two. Ask us if you're not sure.

Outlook on the web and new Outlook

1. Select Settings (gear icon) > Accounts > Signatures.
2. Select New signature (or Add signature), give it a name, then type and format your signature.
3. Choose whether it's added to new messages and to replies and forwards.
4. Select Save.

Classic Outlook (Windows)

1. Select File > Options > Mail > Signatures.
2. Select New, give it a name, then type your signature in the box.

Tips

• Keep logos small. Large images make emails bigger and are often blocked.
