We are using O365 Exchange Online. We have users ability to directly add add-ins disabled, but we have several that we activate globally and set to mandatory (deploy all).
For a user with Outlook IOS, they go to outlook and get an error message that they do not have permissions to add add-ins (which is desired).
I don't see the option to do anything with Add Ins for Android
How do we use Add-Ins in the Outlook for Mobile apps?
Looks like it was announced back in September for Android, but I guess it still hasnt rolled out? https://blogs.office.com/en-us/2017/09/08/your-favorite-apps-now-in-outlook-on-android/
