In September, Microsoft announced the impending deprecation of its Smart Screen e-mail spam filter service for Exchange Server and the Outlook e-mail client.
So, I made the decision to upgrade my domain from Windows 2003 SP2 to Windows 2008 R2.
So, I installed a new server, joined it to the domain and promoted it to a domain controller.
I created everything, including the mailbox and waited for everything to sync. This is a very small network and things take just a few minutes to execute. I tried different variations and ways to make this work, but nothing would or could create a mailbox on the Exchange server.
Just to keep things running, I had a few test accounts set up from earlier, so I deleted one of those accounts and re-associated its mailbox with my new user. I commented on the Microsoft Exchange Team Blog article, but have not received any responses.
In order to troubleshoot this I opened up ADUC and changed the view to “Advanced Features” (Open ADUC - Advanced Features) and then choose the “Security” tab and clicked on “Advanced” button which revealed the following: As you can see on the above example the user concerned does not have the “Allow inheritable permissions from the parent to propagate to this object and all child objects…” check box set.
