Yeah, that may be a problem... The users of the site I want to add these to are not necessarily technically inclined, so compatibility issues may cause more problems than it's worth. I use Office/Outlook 2007 at work, but I don't use Office at home, so I'm guessing the .ics files I'd create probably wouldn't work with older versions. RSS is a good idea, but many, if not most, of the users probably have no idea what RSS is, let alone how to use it.
The site is for a charitable organization, and they have fund-raising events every couple of months. I was hoping I could have an easy way for people to add event information to their copies of Outlook, but with the different compatibility problems between different Outlook versions, this might not be a good idea...
Thanks, Eran.
