Problem with DAV integration for calendar in Outlook

[bfeddes]

I already read a discussion where a different Yeti user had this issue, and that discussion was unable to resolve my problem. I attached some screenshots along with a description of what isn't working.

Yetiforce Key setup:

My configuration using CalDav Synchronizer on Outlook works and says the connection test was successful, as shown below:

However, when I try to integrate I get this error:

All errors are the same, and there is 4 of them. "System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. --> System.NullReferenceException: Object reference not set to an instance of an object."
at DDay.iCal.iCalDateTime.get_UTC()
etc... as shown in the screenshot.

When I grab a specific .ics file from the dav.php page, that is able to be added to the Outlook calendar, but the automatic synchronization does not work.

Some steps I have already taken as instructed by the other discussions I read:

1. change from false to "Private" in the /Components/Dav.php folder as shown below:
   

Beyond that from what I read, nothing has helped. Was hoping someone with more knowledge could help me out as this is a feature our company really wants to implement.
