Your emails from Outlook for iOS automatically include a “Sent from Outlook for iOS” signature. This is a default setting applied to all new accounts on the mobile app. Many business users prefer to send emails without this promotional tag. This article explains how to disable this default signature and manage your email footer on your iPhone or iPad.
Key Takeaways: Removing the Mobile Signature
- Settings > Mail > Default Signature: This is the primary menu to delete or replace the default “Sent from Outlook for iOS” text.
- Per-account signatures: You can set a unique signature for each email account you have added to the Outlook mobile app.
- Blank signature field: Leaving the signature field completely empty is the only way to ensure no text is appended to your sent messages.
Understanding the Outlook for iOS Default Signature
The Outlook for iOS app adds a “Sent from Outlook for iOS” signature by default for every new email account you configure. This is a promotional tag set by the app developers. It is separate from any signature you may have configured in the desktop version of Outlook or in your mail server settings.
The signature setting is managed within the app itself. You need the Outlook app installed on your iOS device. The process involves navigating to the app’s settings menu. You can set a different signature for each email account, or remove the signature entirely.
Steps to Delete the Default Signature
- Open the Outlook app
Launch the Outlook application on your iPhone or iPad. Ensure you are signed into the email account where you want to change the signature. - Tap your profile picture
In the top-left corner of the app’s main mail view, tap your profile picture or account icon. This opens the account management sidebar. - Open the Settings menu
Tap the gear icon labeled “Settings” at the bottom of the sidebar that appears. - Select your account
Under the “Mail Accounts” section, tap the name of the specific email account you want to configure. - Navigate to Signature settings
On the account settings screen, find and tap the “Signature” option. This will open a text editing field. - Delete the default text
The text field will contain the phrase “Sent from Outlook for iOS”. Tap and hold to select all the text, then tap “Delete” on the keyboard. To have no signature, ensure this field is completely blank. - Save the change
Tap the “Back” button in the top-left corner. The app automatically saves your changes when you exit the signature editing screen.
Common Mistakes and Limitations
The signature reappears after an app update
Major app updates can sometimes reset certain preferences. If the default signature returns, you need to repeat the steps above to clear the signature field again. Your custom signatures are usually preserved, but a blank field may be reset.
Setting a per-account signature does not work
You must configure the signature for each email account individually. Changing the signature for one account does not affect others. Go to Settings > select the specific account > Signature to set a unique signature for that address.
The signature still shows on replies and forwards
The signature setting applies to new messages, replies, and forwards. If a signature appears in a reply, it is the one currently set in your Outlook for iOS app settings for that account. Check the signature setting for the account you used to send the reply.
Default vs Custom Signature Options
| Item | Default “Sent from Outlook for iOS” | Custom or Blank Signature |
|---|---|---|
| Text Content | Fixed promotional phrase | Any text you enter, or empty |
| Configuration | Automatically applied to new accounts | Manually set per account in app Settings |
| Professional Appearance | May appear informal for business | Allows for a formal company footer |
| Persistence | Can reappear after major app updates | Stays as set unless manually changed |
You can now send emails from your iPhone or iPad without the automatic promotional tag. For a more professional look, set a custom signature with your name and contact details. An advanced tip is to use a simple dash or two hyphens (–) as a signature separator, which is a common standard in plain-text email communication.
