Identify a Physical Mobile Device from an Office 365 Device ID
Question details
The user needs to determine how to identify a physical mobile phone that is quarantined for approval by using its Office 365 or Exchange mobile device ID.
- Product
- Microsoft 365 / Exchange Online
- Device & OS
- not provided
- Scenario
- An administrator needs to approve a quarantined mobile device but only has the device ID, which does not clearly indicate the physical phone or its owner.
- Observed behavior
- The device ID acts as a management record identifier and does not inherently reveal the phone's hardware model or physical owner, making it difficult to approve the correct device.
Ensure you have administrative privileges for the Microsoft 365 admin center, Exchange Online, or Microsoft Intune to access and review enrolled device management records.
Cross-reference the Device ID in Exchange Online or Microsoft Intune
Use your administrative portals to compare the quarantined device ID against enrollment records, user accounts, and operating system data.
A device ID is primarily an identifier for the mobile partnership or management record. By itself, it may not reveal the physical phone's model or owner.
To properly identify the device, you must compare the ID provided in the quarantine notification with the active records in your management portal. Matching the ID with the user's account, device name, operating system, enrollment information, and last activity time will help you pinpoint the physical phone.
Navigate to the Microsoft 365 admin center or Microsoft Intune endpoint manager and log in with your global or device administrator credentials.
Go to the 'Devices' or 'Mobile Device Management' section to view the list of all enrolled, managed, and quarantined devices in your organization.
Enter the specific Device ID from your quarantine notification into the search bar to locate the exact management record.
Review the details of the located record, specifically looking at the associated user account, device name, operating system, and last sync activity to confirm the physical device's identity before approving it.

Frequently Asked Questions
Why doesn't the Office 365 device ID show the phone model directly?
The device ID acts as a software identifier for the mobile partnership and management record rather than a hardware serial number. It requires cross-referencing with user accounts and operating system data in the admin center to pinpoint the physical device.
Where can I manage quarantined mobile devices in Microsoft 365?
You can manage quarantined devices through the Exchange admin center under Mobile Device Management, or by navigating to the devices section within the Microsoft Intune admin portal.
Can I approve a quarantined device without knowing its physical owner?
While technically possible in the admin center, it is strongly advised against for security reasons. You should always cross-reference the device ID with user enrollment information to verify the owner and ensure compliance before lifting a quarantine.
