Block iMessage backup to iCloud

Hello.  Trying to block the backup of messages on some iPhones. ABM managed, ADE-enrolled devices. I see through both the restrictions template and settings catalogue, this is not available. So I thought maybe I could do this through an App configuration policy. Turns out, no - because Messages is not listed under public apps. Then I thought to do it through App Protection policies... but again, Messages does not appear. But I noticed App Protection policies can apply to managed apps, so why not just add Messages to my managed apps? And conveniently, the "Add app" tool has a "built-in app" button. But none of those apps are built-in apps. Not one of them, from what I can tell. 

Anyone able to help out here? This seems.. bizarre.

  • Hi underQualifried!

    You’re right, messages isn't listed under the apps where you can apply specific policies. Unfortunately, Apple doesn't currently provide a direct way to block iMessage backups specifically through ABM or ADE. The "built-in app" option in App Protection policies doesn’t apply to Messages since it’s not considered a managed app.

    You might have to explore other options, like restricting iCloud backups entirely or using a device management solution that offers more granular control. But as of now, iMessage backup control doesn’t have a clear path through the available tools.

    Hope it helps!

      Thought I replied to this... anyway, thanks - confirmation does help. I've been looking thru the documentation a bit more, re: app  protection policies. I FEEL like these should be able to do what I want, shouldn't it? Isn't that part of app protection? 

      Aside from that, I also found a sort of out-of-place page with a list of bundle ids for built-in (to iOS) apps within the documentation. It  doesn't really describe HOW they're intended to be used, but it seems like I can use the messages bundle ID to add restrictions SOMEWHERE. Wondering if I add messages as a managed app, and disable iCloud backup through the assignment tool, if it will apply - or if it would require uninstalling/reinstalling for all devices. 

      Going to test, but if you have insight, I'd welcome it
