In a previous post I outlined doing some planning with the different options for sending email out of AX2012. While not email but related there is an ability to sync Contacts, tasks, appointments from AX2012 into Outlook. This has always been a client side call to Outlook which causes problems if you deploy the AX Client on a remote desktop server as Outlook will also have to be deployed there for the sync to work.
In AX2012 R3 CU8 that was just released there is a new feature that allows you to setup the sync to be with Exchange server and avoid the sync to Outlook. The sync is now handled via a web services to Exchange. This is a walk through of that the feature looks like and the setup.
It’s important to note there is a manual setup in getting this setup as noted in the KB2984369 you need to download the Microsoft Exchange Web Services Managed API 2.0. You will see what I mean in the above video.
