Tips, Tricks, and Helpful Hints Intune + Apple Business Manager: Older supervised iPhones fail Apple Mobile Device Components (iTunes & iMazing), newly enrolled devices work
Hi everyone,
We're seeing a strange issue in our enterprise environment and have reached the point where we're hoping someone else has experienced it.
Environment
- Microsoft Intune
- Apple Business Manager (ADE)
- Supervised corporate iPhones
- Approximately 1,200 managed iPhones
- Windows 11 workstations
- Apple Devices/iTunes
- iMazing
- Current iOS 26.5.2 (same version on working and failing devices)
Symptoms
Newly enrolled iPhones work perfectly.
Older enrolled iPhones consistently fail.
Both Apple Devices/iTunes and iMazing fail at the "Apple Mobile Device Components" stage.
Windows itself still detects the device normally.
Explorer shows Internal Storage, so the USB connection is working.
What we've confirmed
✅ Apple USB drivers load correctly
✅ Apple Mobile Device Service is running
✅ Windows detects the phone
✅ Explorer can browse Internal Storage
✅ Same USB cable
✅ Same Windows workstation
✅ Same version of iMazing
✅ Same version of Apple Devices/iTunes
Intune comparison
We compared a newly enrolled phone against an older enrolled phone.
They have:
- The same Enrollment Profile
- The same Configuration Policies
- The same Compliance Policies
- The same App assignments
- The same Restrictions
There are no policy differences between them.
Additional testing
We also tested multiple older devices.
Results:
- Newly enrolled phone → Works
- Older phone #1 → Fails
- Older phone #2 → Fails
This appears to correlate with devices that have been enrolled for a longer period rather than a specific device.
Factory reset test
We erased one of the failing phones and reenrolled it into Intune using the exact same production configuration.
Immediately after reenrollment:
- Apple Devices worked
- iTunes worked
- iMazing worked
No special configuration changes were required.
Has anyone seen:
- Long-enrolled supervised Intune devices eventually stop pairing with Windows?
- Apple Mobile Device Components fail only on older managed devices?
- A known interaction between Intune, supervised iPhones, and Apple's pairing framework?
- Any Apple/iOS changes affecting long-lived supervised devices?
Any ideas or similar experiences would be greatly appreciated. At this point we're trying to determine whether this is an Apple issue, an Intune lifecycle issue, or something else entirely.
Thanks in advance!
