Fix: Use autodiscover service to receive connection settings during OpenMsgStore() call

Today we released the hotfix which provides the ability for non-Outlook MAPI applications to use the Autodiscover service to receive connection settings during IMAPISession::OpenMsgStore, when the target is an Exchange mailbox.

To enable this ability, install April 5, 2016, update for Outlook 2013 (KB3114941), and then follow these steps described at https://support.microsoft.com/en-us/kb/3114974

Hope this helps.
