I need to create some sort of group/dynamic distro group/distro group/whatever in the Exchange Admin Centre where we can have internal and external email addresses included. This is my end goal, but I'm not sure how to accomplish it because:
- DDLs can't have manually added email addresses or include another DDL/DL
- Adding rules to a DDL uses "and" syntax, there's no "or" syntax so if you have two rules, a user has to match both criteria
- We can't keep creating a new attribute for every DDL and even if we did how the heck could we have someone be a part of two different DDLs if we used this model?
