ActiveSync Devices

This report lists every mobile device partnership registered against a mailbox in the selected tenant, one row per device. It shows what each device is, when it last synchronised, and whether Exchange Online currently allows or blocks it, so you can find stale partnerships and quarantined devices without opening Exchange Online PowerShell.
The properties returned are for the Exchange Online PowerShell command Get-MobileDevice. For more information on the command please see the Microsoft documentation.
Device Access State is the column the row actions work from, and is normally Allowed, Blocked, or Quarantined. CIPP adds one column of its own, Sync Info Note: where the row is Outlook for iOS or Android, it explains that those apps use modern authentication and do not report ActiveSync sync times, which is why their sync columns can look empty or out of date.
Allow Device
Allows the device to synchronise with the mailbox. Greyed out where Device Access State is already Allowed.
Block Device
Stops the device synchronising with the mailbox. Greyed out where Device Access State is already Blocked.
Delete Device
Removes the device partnership from the mailbox entirely. This cannot be undone.
More Info
Opens the Extended Info flyout with the full details for the selected row.
Each action confirms first, naming the device and the mailbox it belongs to. Allowing and blocking are settings on the mailbox rather than on the device, so a device that synchronises several mailboxes needs the action running against each of its rows.
We value your feedback and ideas. Please raise any feature requests on GitHub.
