I'm developing an Outlook Add-In for enterprise customers that they will be hosting themselves, so I assume the best method for deployment is by using using the Admin Center to deploy a custom Add-In.
When deploying a Store Add-In, the Admin can be prompted to accept licence terms and view the Add-In's privacy policy.
Is it also possible for a custom add-in to show a prompt like this?
Unfortunately, it is not possible for a custom add-in today to show a License + Privacy Policy prompt.
We track Outlook add-in feature requests on our user-voice page. Please add your request there. Feature requests on user-voice are considered, when we go through our planning process.
