I have an existing application which is native to 2003 (mde format) which uses the Outlook API to synchronize meetings in the outlook calendar with my application database. It has worked fine in the past, interacting normally with Outlook 2007 and 2010 instances, but I now have a client using Outlook 2013 with Office 365 licencing and the process crashes with an obscure error. There is also a process which synchronizes contacts and that runs fine too. Everything is 32-bit - the application and the Office 2013 installation, etc.
Can anyone point me to any documentation on what might have changed with the API as far as compatibility to Outlook 2013? I found some references to recent API changes, but nothing relating to the methods and properties I'm using.
