Installation & advice
Set a signature in Outlook mobile
Outlook for iOS and Android has its own signature setting. Rich formatting support varies by platform and app version; a simple text fallback is the most dependable.
iOS and Android
- Open your profile icon, then Settings (gear) → Signature. Enable Per Account Signature if you want different details for each account.
- Enter your name, role and business contact. If your editor accepts pasted formatting, test links and images in a sent message before relying on it.
- Do not assume a desktop signature automatically appears in mobile messages.
Menus vary by release and account policy. Instructions reviewed 19 Oct 2026. Official documentation ↗
