Setting up a shared mailbox in Microsoft Outlook is easy to do and has many benefits for some users. Here's how you can make it happen.

1) open shared mailbox in outlook. Create rule that when new email received, forward the email as attachment to all the recipients (best practice would be to create an AD group for this) ...

I noticed that the shared mailboxes all only had "outlook on the web" and "exchange web services" checked under the "manage email apps" setting.
