we're trying to make a email-adress (support@domain.com) shared by two users (user1@domain.com, user2@domain.com)..
we created a shared mailbox (exhange 2010) and give user1-2 access to it.. it works great, they can access mail from the outlook.
however, that suppor@domain.com email address is NOT in proxyAddresses properties of Active Directory objects for user1 and user2.
–
We have a third party system that pull information from AD and it cannot detect that user1 and user2 has access to support@domain.com, since it parses proxyAddresses property of AD objects.
exchange UI does not allow adding that address as an alias.
is there a way to manually add that email to those users, from AD maybe?

You can't assign the same
proxyAddressto two objects in the Active Directory-- that's not a workable configuration. (Yes-- I've seen cases where people have managed to do it-- it doesn't work like you want it to because it's not supposed to ever happen.)You have two choices-- either what you're already doing, or creating a mail-enabled group and making both users a member.
It sounds like your users like the shared mailbox (probably because they can see if items have been read / acted-upon, etc). Using a group to deliver to both users wouldn't give them that "collaboration" ability, which would probably not be desirable.
I'd think hard about why you care if the third-party system "knows" that these two users have access to that mailbox. Why does it need to "know" this? What does it change if the third-party system just sees the shared mailbox as a "user" and delivers email to it accordingly, since, in the end, the appropriate people will still have access to the shared mailbox?
