Since my fresh install of OS X 10.9 Mavericks I have problems syncing my Calendar with the MS Exchange server (version 2008).
When I add an appointment in the Exchange calender in Calendar on my OS X machine, it gets created without any errors. After this, I sync this appointment with the Exchange server CommandR. Now I expect this new appointment to be living on the Exchange server and I expect this appointment to be synced with my other devices (iPhone and company website), and it does.
But when I reverse things and create an appointment in the Exchange calendar via the company website it gets synced to my iPhone, but it does not show in the OS X Calendar app. What about invitations? I receive the invites in my mail inbox and in my Calendar inbox, but excepted invitations do not show up in my OS X Calendar as well.
For debugging I created another account on my OS X machine, but as a different user the same problems occur. I also used another mac running 10.9 and the same problems occurred, but no problems occurred using my iPhone or a windows PC. There were also no problems when I logged in using the same exchange server but a different account.
With the symptoms described above, it is likely there is a problem with the MS Exchange server. But my colleague, also running OS X 10.9 has not encountered any problems with calendar syncing.
Other versions of OS X worked fine with my setup. Did communication with the MS Exchange server change in OS X 10.9? Are there other possibilities that causes my problems?
Unfortunately the IT department still does not support OS X machines and are therefor not willing to help out.
