So, we stopped there and didn’t post any blog on upgrading Exchange 2016 CUs because of this error.As explained in part 1, we need to use Web access proxy to use Multi-Factor Authentication for RDWeb.I did a bit of digging into it and think I’ve worked a few things out that make the whole situation a bit clearer. We need to look at how often Lync polls Exchange for the free/busy information, and then how often your calendar state is published to your Lync presence change from Available to In a Meeting based on the free/busy data that was retrieved from Exchange.

I’ve had a few questions come up lately around when Lync 2010 polls Exchange for free/busy information and how/when presence state is updated based on your calendar.
