It is very simple but it is not unless you don’t know. First time I had no idea how and where to do it until I spoke to TMG MVP Richard Hicks. Before getting in contact with him I’ve made a number of calls to Celestix and our reseller J
So how to do it?
What you have to do it Enter the AGREEMENT NUMBER (7 digit numbers starting with V as for volume. Don’t enter V – digits only) under License Details as shown below.
Once you are done here then set the dates as per your Microsoft license agreement.
Apply it- Cheers:)
