Update 09/09/2025: A fix for the known issue will be rolled out with Intune's September (2509) release, ahead of Apple's latest terms and conditions expected on September 22, 2025.
When Apple updates the Apple Business Manager Terms and Conditions (T&C), an IT admin will need to accept these new terms when using Apple School Manager (ASM), Apple Business Manager (ABM), Apple Volume Purchasing Program, and Automated Device Enrollment to ensure that the managed devices can continue communicating with Microsoft Intune, or any other MDM provider.
How does this affect me?
This will only affect you if you have MDM-managed devices and use any of the following programs:
- Apple School Manager
- Apple Business Manager
- Automated Device Enrollment (formerly known as Device Enrollment Program)
- Apple’s Volume Purchasing Program
Managed devices will not be able to sync with Intune until the new Apple T&C is accepted. The Intune service receives the error – “T_C_NOT_Signed” from Apple. If you use any of the listed programs, simply login to the appropriate URL highlighted in the support article from Apple here: https://support.apple.com/102069. Once you’ve logged in and accepted the new T&C, managed Apple devices will once again be able to communicate with Apple’s device management servers.
Known issue:
When Apple releases new T&C to the Apple Business Manager or Apple School Manager portal, the manual sync between Intune and ABM/ASM for the token will be temporarily disabled, even after the T&C has been accepted, until the next 12 hour automatic sync is completed. This applies to all Apple Automated Device Enrollment (ADE) devices.
Workaround
To manually trigger a sync, even when the sync button is disabled, simply create a new enrollment profile and save it. The profile doesn't need to be assigned to any device, and its contents are irrelevant. Once saved, this action will trigger a sync and assuming the new T&C has been accepted, resolve the issue. The new profile can be deleted immediately afterward.
