Outlook signature generator + install guide

Outlook is the pickiest email client out there — its desktop renderer ignores half of modern CSS. SignatureKit templates are built to survive it. Create yours free, then paste it in with the steps below.

Outlook on the web (Microsoft 365, outlook.com)

1. Click the gear icon (⚙️) top-right → Settings.
2. Go to Mail → Compose and reply (or search for “signature” in Settings).
3. Click + New signature, give it a name, and click into the big editing box.
4. Paste with Ctrl+V (Mac: Cmd+V) — formatting, logo and social buttons come along.
5. Under Select default signatures, choose it for New messages and Replies/forwards.
6. Click Save.

New Outlook for Windows / Mac

1. Open Settings (⚙️) → Accounts → Signatures.
2. Click + New signature, name it, paste your signature into the box.
3. Set it as default for new messages and replies, then Save.

Classic Outlook (desktop)

1. File → Options → Mail.
2. Click the Signatures… button.
3. Click New, name the signature, then paste into the edit box below.
4. Assign it under Choose default signature (New messages / Replies and forwards) → OK.

Tips for Outlook specifically

• Paste, don't rebuild. Manually re-typing a signature in Outlook loses the layout. Always paste the HTML.
• Round corners may become square. Classic Outlook's Word engine ignores border-radius — our templates are designed so this only softens the styling, never breaks the layout.
• Microsoft 365 sync. Signatures set in Outlook on the web sync to new Outlook and Outlook mobile automatically. Only classic desktop Outlook needs its own install.
