We had a customer that was unable to approve an ActiveSync device via the ECP console. The device in question would simply sit in the quarantine section continuously. We were able to block the device however, but this didn’t help the user!

So to show a list of devices for the user we ran the following command:

Get-CASMailbox <mailbox> | fl activesync*

This showed something like:

So to clear your blocked devices you can run:

Set-CASMailbox <mailbox> -ActiveSyncBlockedDeviceIDs $null

Now a get as above shows:

So to re-add the device to the allowed list we can run:

Set-CASMailbox <Mailbox> -ActiveSyncAllowedDeviceIDs “Appl0FJM431C7FT5”

In this case we actually added two devices – Set-CASMailbox <mailbox> -ActiveSyncAllowedDeviceIDs “ApplF5RL78E9DFHW”, ” ApplFE9L785RDFHW”

After this the user reported all was working as expected.
