Outlook on the web (Outlook.com / Microsoft 365)

  1. Click the gear icon → View all Outlook settings.
  2. Go to Mail → Compose and reply.
  3. Click + New signature, name it, and paste into the editor.
  4. Set it as the default for new messages and replies, then Save.

Outlook for Windows (desktop)

  1. Open a new email, then Insert → Signature → Signatures…
  2. Click New, name the signature, and paste into the edit box.
  3. Choose it as the default for new messages and replies/forwards, then OK.

Outlook for Mac

  1. Outlook → Settings → Signatures, click + and paste.
  2. Assign it to your account as the default for new mail and replies.
Formatting looks off after pasting? Outlook's desktop editor sometimes re-flows tables. Use the Copy HTML code option instead and, for the web version, paste with Ctrl+Shift+V avoided — a normal paste keeps the formatting.
