Trying to send out a package to an Android device, I receive an error code -50 "Could not send C2DM notification to device"

What To Do
There might be possible reasons for this issue.
One might be that you have registerd another Google account to be able to use C2DM and entered the newly created account in the Sophos Mobile Control web maangement. By doing this, it is not possible anymore to manage devices which communicated via the old C2DM account.
You should change the C2DM account again to the account used beforehand.
