Does anybody know if it's possible to extend the functionality offered by the Exchange E-mail address policies, i.e. call out to a custom component to determine the address?
We are implementing a new system that manages AD data, and that will quite likely change existing account data, i.e. first names, middle names and last names. This would result in the Exchange policy updating the email address which is not what we want. We want addresses to remain unchanged.
My desire is that the policies could be modified somehow to only take effect on NEW accounts, not existing ones, but the policy generating wizard is not that flexible, it has no concept of dates or other AD attributes that could be used to determine the trigger.
I'd love to be able to drop in a .net component or something similar, that would allow precise definition of the policies.
