How to upgrade your default Email Address Policy
During some upgrades of my customers to E2K7 I've faced the need to upgrade my recipient update policies, formerly managed by Exchange 2003 RUS now they need to be managed by Exchange 2007.
So first step, check the current policies:
get-EmailAddressPolicy
Next step set the policies to be managed for exchange:
set-EmailAddressPolicy "NAME OF THE POLICY" -includedrecipients AllRecipients
Just repeat this step for every policy you need to upgrade.
I intend to publish a full Upgrade guide, just have to manage the schedule :)
