I use Apple MobileMe and Outlook 2007 (on Vista) to organise my work and home calendars and publish them to my iPhone as well. I have two calendars set up, Work and Home. The Work calendar is set up as the default for my computer at work, and the Home calendar is set up as the default for my computer at home. I can create appointments from either computer in either calendar, or even from my iPhone, and they sync instantly to the rest.
All has been working flawlessly for a few months. However, and since one week ago or so, my home computer has stopped syncing its calendar. It doesn't "receive" any changes that I made to the MobileMe calendars from my work computer or iPhone, and the changes that I make on my home computer are, apparently, not transmitted to MobileMe, because they never appear on the MobileMe calendar or the other computers.
Contacts and other sync information works fine. It is only calendar items that fail. I have no error messages or any other evidence of failure.
I have checked that my Windows is up to date, that I have the latest version of iTunes and the MobileMe Control Panel, and I have performed the basic checks suggested by Apple on their MobileMe support page.
Can you help? So many thanks.
