I’ve updated the iCal-Invite-Fix script again. This time to allow for adding multiple Exchange servers to the script so that you should only need a single script. The set-up is slightly more complex. As the image above shows there are now only 2 properties, both of which are lists. These lists work together as an array; which means the order of the list items is crucial.

• exchange_fragment contains unique fragments of the TZID that the Exchange server sends.
• ical_tzid contains the tzid info that iCal expects to see.

If you have any problems setting it up let me know. This post has all the info for the script. Download the iCal-Invite-Fix script.
