After one of the frimware updates, this was no longer possible and you could only have one or the other. My question is what was the problem with having both enabled? It worked fine for me... in fact, the change that brought the inability, broke my configurtions.
My Exchange 2010 configuration:
Most users have both part 1 and part 2.
Part 1 -
Our company has several brands which requires the majority of our users to be able to send from multiple domain accounts, i.e. firstname.lastname@example.org (default), email@example.com (extra), firstname.lastname@example.org (extra).
In order to accomplish sending from the extra e-mail addresses on Exchange, you create a distribution group with bob's AD account as the only member and you have email@example.com as the only e-mail address. In ADUC, you locate the new distribution group and, under the Security tab in properites, you give Bob's AD user "Send As" permissions. This allows Bob to receive all e-mail for each brand in a single mailbox and send as individual brands/domains, as needed.
Part 2 -
Some users also have multiple e-mail aliases, i.e. firstname.lastname@example.org, email@example.com, firstname.lastname@example.org. These aliases are all controlled in the properties of the user's mailbox, under the e-mail addresses tab.
The problem I am having:
When only the Unify Aliases is enabled in each (or a particular) domain -
- A message bound for a user's distribution group is flagged for quarantine.
- The message sits in the quarantine box.
- The quarantine summary e-mail is sent.
- The user clicks on any of the links to interact with the quarantined message.
- Unable to login to the quarantine inbox.
- A message bound for a user's alias is flagged for quarantine.
- The message is delivered directly to that user's mailbox, completely bypassing the quarantine.
