The Outlook app on Android has no HTML signature field, and it often drops images. Install the full signature on a computer if you need the logo. Text and links can still be pasted into the app.
-
Get the signature into an email
Install it first in new Outlook, Outlook for Mac or Thunderbird. Send yourself an email that includes the signature.
-
Copy it on your phone
Open that email in the Outlook app. Press and hold the signature, drag the handles so the whole signature is selected, then tap Copy.
-
Paste into settings
- Tap your profile icon, then the settings gear.
- Tap Signature for that account, clear the default text, then press and hold to paste.
- Go back to save, then compose a test email.
This phone signature is separate from Outlook on a computer. If the logo disappears, send from the computer or from Outlook on the web.
