Update the email signature to add your contact details, a quote, or other information that you want to appear in every message you send. Instructions in this article apply to the Outlook mobile app for iOS 12 and iOS 11. Change the Email Signature in the Outlook iOS App The Outlook mobile app for iOS supports Microsoft and non-Microsoft email accounts such as Gmail and Yahoo. You can use these instructions to change your Outlook, Gmail, Yahoo, and other email signatures as long as the account is listed inside the Outlook app. To change your email signature in the Outlook app and make a different signature for each of your email accounts: Open the Outlook app, then tap the three-line menu in the upper-left corner. Tap Settings (the gear icon). Scroll to the Mail section. Tap Signature. In the Signature screen, erase the signature and enter a new signature. To set up a different email signature for a different account, turn on the Per Account Signature toggle switch. When you're done, tap the back arrow to return to the Settings screen. The new signature appears in the Signature section. If Per Account Signatures is enabled, the signature does not appear. Tap the Exit button to return to your mail. Edit the Signature Temporarily Another way to change your email signature in the Outlook app is to delete it from individual messages on an as-needed basis before you send the message. For example, if you made a custom signature, deleted the signature, or kept the original default signature, but want to change it for the email you're about to send. To edit the signature on a per-email basis, scroll down the message until you reach the bottom where the signature is. Remove, edit, add more text, or delete the signature before sending it.

If you start a new message, the signature stored in the settings will always take precedence.
