    To follow Apple's terms for acceptable enrollment program traffic, Intune imposes the following restrictions:
-   - A full sync can run no more than once every seven days. During a full sync, Intune fetches the complete updated list of serial numbers assigned to the Apple MDM server connected to Intune. If an ADE device is deleted from the Intune portal, it should be unassigned from the Apple MDM server in the ADE portal. If it's not unassigned, it won't be reimported to Intune until the full sync is run.

+    > If a device is deleted from the ADE devices blade, but remains assigned to the ADE enrollment token in the ASM/ABM portal, it will not re-appear in Intune until the next full sync. If you don't want the device to reappear in Intune - you should remember to change it to "unassigned" or another MDM server in the ABM/ASM portal.
    - If a device is released from ABM/ASM, it can take up to 45 days for it to be automatically deleted from the devices page in Intune. You can manually delete released devices from Intune one by one if needed. Released devices will be accurately reported as being Removed from ABM/ASM in Intune until they are automatically deleted within 30-45 days.
    - A delta sync is run automatically every 12 hours. You can also trigger a delta sync by selecting the **Sync** button (no more than once every 15 minutes). All sync requests are given 15 minutes to finish. The **Sync** button is disabled until a sync is completed. This sync will refresh existing device status and import new devices assigned to the Apple MDM server. If a delta sync fails for any reason, the next sync will be a full sync to hopefully resolve any issues.
