How to license a Exchange 2007 EDGE server

If you deploy and configure an Exchange 2007 environment with a EDGE server without registering license keys before creating the subscription you can have problems licensing the EDGE server. There will be a warning message when starting the Exchange Management Console on any of the HUB/CAS/Mailbox servers that the EDGE server is unlicensed.

If you run Get-ExchangeServer select name,productid,*trial* you will get a similar output:

Name:	<ServerName>
ProductID:
IsExchange2007TrialEdition:	True
IsExpiredExchange2007TrialEdition:	False
RemainingTrialPeriod	26.22:52:33.0692266

To solve this issue you need to recreate the EDGE subscrition between the EDGE and HUB server:

1. Logon to the EDGE server
   1. Start Exchange Management Shell
   2. New-EdgeSubscription -FileName <Filename.xml>
2. Copy the XML file to the HUB server
3. Logon to the HUB server
   1. Start Exchange Management Console (EMC)
   2. Go to Organization Configuration > Hub Transport
   3. Right click and choose "New Edge Subscription..."
   4. Follow the wizard
   5. Start Exchange Managment Shell (EMS)
   6. Start-EdgeSynchronization
      Verify that "Result: Success" appears
4. Delete the XML-files that you created

Now the EDGE server should be licensed when starting the EMC.
