Enable Outlook Web Add-in only on the Web

Question

I developed an Outlook web-based add-in. To install it, I added the manifest file from the "Manage add-ins" page in OWA: https://msdn.microsoft.com/en-us/library/office/fp142256.aspx. The add-in is showing up in both Outlook Web App and Windows Desktop App.

Is there a setting or code change need to be done to make the add-in available only in the Web App.

Answer 1

We have no such capability - we'd like the platform to provide users with consistent experience regardless of Outlook client/platform they use. Would you mind sharing why would you like your add-in to show up in OWA but not in desktop Outlook?
