0 of 6 steps done

Open Settings

Tap your Outlook profile picture or initials at the upper left, then tap the Settings cog.
Find Signature

Under the Mail settings, tap Signature. If needed, scroll down the settings list.
Choose per-account signatures

If you use more than one account, turn on Per Account Signature. Locate your work address so the business wording does not replace a personal account’s sign-off.
Enter your work details

Delete the default text and type the approved wording. A simple mobile version can contain your name, Initech Solutions, work phone and work email on separate lines.
Save and return

Tap the tick or save control if shown, then go back to Inbox. Some versions save as you leave the page; reopen Signature to check the text remained.
Test a new email

Tap Compose and check the From address. Confirm the signature appears at the end, then send a short test to yourself and check the received message.

Use plain, short contact details for dependable mobile formatting. The mobile signature editor may not reproduce a complex desktop logo or table layout.
If the office adds a company signature automatically, follow its instructions to avoid duplicates.

No signature appears

Check the correct account and default signature selections. Create a new message after saving; an already-open draft may not update.

There are two signatures

The company may add one automatically after sending. Ask the office which signature should be used before adding another.

The signature is different on my phone

The Outlook mobile app has its own signature setting. Configure and test it separately rather than assuming every app synchronises signatures.

Menu names can change as Microsoft updates the apps. These official pages include further instructions.
