Outlook.com (Outlook on the web) HTML email signature installation guide

This guide covers Outlook.com — also called Outlook on the web or the Outlook web app. It supports HTML signatures: you paste the rendered signature (not raw code) into the signature editor.

1Create and download your signature
1. Design and save your signature in Mirosign (an active subscription is required to download).
2. Click Download HTML, open the file in Chrome, Edge or Firefox, then select it all (Ctrl/Cmd + A) and copy (Ctrl/Cmd + C).
2Open the signature settings
1. In Outlook.com, click the Settings gear (top right).
2. Go to Accounts → Signatures (older layouts: Mail → Compose and reply).
3. Click + New signature and name it Mirosign signature.
3Set the base font first (recommended)

To stop Outlook overriding your styles, click inside the signature box and use its toolbar to set a base font, size and colour first — for example Arial, 10pt. Then paste on top.
4Paste and save
1. Click in the signature box and paste (Ctrl/Cmd + V).
2. Set Mirosign signature as the default for new messages (and replies/forwards if you wish), then click Save.
3. Start a New message to test.
