Having trouble allowing access to ActiveSync for a mobile device? You set Allowed through the GUI but it comes back Access Denied?
Try Powershell…
Start by discovering the DeviceID of the stubborn device with a Get-MobileDeviceStatistics –Mailbox user@domain.com
command.
You’ll be looking for DeviceID
and the current DeviceAccessState.
Get-MobileDeviceStatistics
-Mailbox jdoe@domain.com
Once you know the DeviceID
you can enter the following command to allow that device to utilize ActiveSync.
Note the DeviceID at the end of the
command.
Set-CASMailbox
-Identity jdoe@domain.com -ActiveSyncAllowedDeviceIDs
G5CV17DITH25F0P91LHFG46FMG
To verify your work rerun the Get-MobileDeviceStatistics command to see if DeviceAccessState now
shows Allowed.
Get-MobileDeviceStatistics
-Mailbox jdoe@domain.com
