Just a quick update to the issue a lot of folks found when working with their calendars when the MMS 2012 Schedule Builder went live for everyone on March 6th.
As we noted on March 7, 2012, the Outlook Sync option wasn’t working for anyone. After being notified, the MMS team fixed the issue Internet Explorer and suggested a fix may be on the way for non-Microsoft browsers (Chrome, Firefox, Safari, et al). However after working on the issue for a day or so, the finished solution is that the Outlook Sync option will only work with Internet Explorer. If you use an alternate browser to access the Schedule Builder, you will no longer see the Outlook Sync option.

BTW: The Internet (.ics) Calendar option works great, and Nick Scott and Chris Stauffer have solutions to make it work with Android and iPhone:
