By default, Active Roles will always connect to the most recent version of Microsoft Exchange in the environment.
In some schenarios, it may be necessary to force Active Roles to use an older version.
Example - Customer installed Exchange 2013 in live environment but wants DL's to be continued to be created in Exchange 2007.
Run the attached script to force Active Roles to connect to Microsoft Exchange 2007 servers.
This can manually be changed for a different version of Microsoft Exchange by changing this line:
EXCHANGE_2000 = 1,
EXCHANGE_2003 = 2,
EXCHANGE_2007 = 4,
EXCHANGE_2010 = 8,
EXCHANGE_2013 = 16
