Incorrect output when you run Get-CASMailbox to view HasActiveSyncDevicePartnership
Original KB number: 3001236
Symptoms
In a Microsoft Exchange Online environment, you run the Get-CASMailbox
cmdlet to view the HasActiveSyncDevicePartnership
attribute. The output shows that the mailbox has no device partnership. However, the user has one or more devices that are synchronizing with their mailbox.
Resolution
To resolve this issue, run the following command:
Get-CASMailbox <Alias> -RecalculateHasActiveSyncDevicePartnership
Note
The RecalculateHasActiveSyncDevicePartnership
parameter was introduced to the Get-CASMailbox
cmdlet in build 15.00.0980.000 of Microsoft 365. To determine the build of Microsoft 365 that the mailbox is on, run the following command:
Get-Mailbox <Mailbox> | fl AdminDisplayVersion
More information
The RecalculateHasActiveSyncDevicePartnership
parameter recalculates the value of the HasActiveSyncDevicePartnership
attribute on the mailbox. The value is automatically updated if it's determined to be incorrect. You don't have to specify a value for the HasActiveSyncDevicePartnership
attribute.
