Share Your Calendar with Other Windows Accounts
Although Windows doesn't make it easy to share a calendar among the other users on the same computer, it is possible. For example, if you and your spouse have different Windows accounts (thus you have different Outlook data folders and calendars), you can manually set it up so both of you can view and edit a calendar.
A good way to share Outlook data among users is to use a Microsoft Exchange Server, but this isn't feasible for most home and small office users because of the money and time required. The best way to share just your calendar with local or network users is to use the Internet sharing capabilities, which we'll discuss in the next section. However, as we'll discuss next, if you want to set up multiple users with the same email accounts in addition to calendars, you could assign the users to the same Outlook data file.
Sharing the same Outlook data file means that everyone will have the same Outlook experiencesharing mail, calendars, tasks, and more. Everyone could access and edit the same Outlook information. However, since this is a crude solution, only one person can have Outlook open at a time. Additionally, other users might even have to be completely logged off; thus you probably can't switch users while still logged in.
To share the same Outlook data file, you first have to export an existing one to a folder that's accessible by the desired users, such as the Public folder in Vista. The default location for the data files in Vista is C:\Users\username\AppData\Local\Microsoft\Outlook. You can simply copy it from there and paste it into the new, public location. Then on each user's Windows account (including the original user account), add the copied data file to Outlook and remove the default one.
