Disabling Outlook signatures in New Outlook and OWA


You are using Microsoft 365 and wish to disable the built-in signature functionality in New Outlook and OWA.


The Exchange admin centre provides the functionality to disable this feature using the Outlook web app policies feature within the Roles menu option.

  • Log on to the Exchange admin center and select the Outlook web app policies option from the menu

  • Click on the policy name, and select the Manage features option from the fly-out

  • Expand the User experience drop down, and deselect the Email Signature option

  • Your users will no longer see the Email signature option under Compose and reply in the Outlook settings window
