Office 365 email question

[Shambler]

There is a DL based on AD group membership.
I'd like to add someone to this DL who is not a part of our company.
A contact object has already been created for this user.
I've added them to the appropriate group in AD.

They aren't showing up in that DL within O365 though. I'm thinking that either Contact objects aren't synch'd or "handled" the same way, as a user Object, in terms of O365 maybe?

Hopefully all of that made sense.

I think I got it.

O365 doesn't work with Contact objects that way. I went into the "Manage My Organization" of the portal, and edited the DL directly.
I was able to add his External Contact (O365 object) to the DL.

Just need to wait for an email or two to go out and confirm if it works.
