Reuse your MSDN benefits with your Org ID
If you are trying to reuse your MSDN benefits with your Org ID but you previously activated against your Microsoft ID then you may need to cancel your subscription to reuse it.
If, like me, you are moving all of your Microsoft ID (was Live ID) corporate stuff over to Organisational Id (Office 365) and you have previously activated your MSDN benefits against your Microsoft ID you have a bit of work to move those benefits over.
