Outlook 2013 crashes when using Schedule Assistant

We are upgrading some from Office 2010 to 2013. With this particular user, they aren't able to use Schedule Assistant in Outlook 2013. Once they're done entering the attendees, they click on Schedule assistant and Outlook crashes and restarts.

Here is the error log:

I've re-build the Outlook profile and removed all the .OST files -- Still crashes

I've tried repairing Office 2013 -- Still crashes

I've uninstalled Office 2013 and performed a clean install -- Still crashes

I've rebuilt the users Windows profile -- Still crashes

As of now, I reverted the user back to Office 2010 Pro Plus and they're able to use it fine now. This is in an exchange environment. Any help would be greatly appreciated.
