Two way iCal sync via Outlook for editors
We need a calendar plugin that will be able to be edited via Outlook (iCal 2-way sync).
This plugin has most of the features we need in a WP calendar system minus the connection with Exchange (or 2-way iCal sync for editors).
We are going to be building a 120+ multisite environment and each of those sites need to have a calendar that can be edited from within Outlook (iCal 2-way sync).
See my other suggestion for a different approach.
