Outlook 2011 also does not support CalDAV.
I am on MAC OS 10.6.8 This has been happening since I decided to use IMAP for my gmail accounts (I was using pop before).
The problem happens on outlook for mac 2011 version 14.3.5 and 14.3.6 (just updated outlook to that version). Outlook for mac 2011 on my iMac works with gmail. Gmail works perfectly on apple mail on the mac book pro and on my iMac. I have the latest version of office for mac 2011 and have now installed it on a new mac book pro but outlook is freezing when i have installed my gmail account. One thing Outlook 2011 does that iCal could take a cue from is that if you have a specific calendar selected, the events for all other calendars fade out a bit.
Categories are common across all calendars there’s no way to have separate categories for each calendar.
