Hi Bulletniebar,
My first question is: Do you have Microsoft Exchange Server or not?
Please read it:
"For many offices, the most frustrating experience related to Microsoft Outlook is finding out that, unless you are using Microsoft Exchange Server, there is no simple, built-in, reliable method for sharing contacts and calendars. That's right, there's no "magic wand" you can wave to enable people to easily share Outlook data without Exchange."
If you don't have Exchange Server, read this:
"The easy, effective, and affordable Outlook shared calendar software alternative to Exchange Server!
Do you have Microsoft Outlook and need to share calendars with your colleagues, but don't want to spend a fortune on software, hardware, and experts required for Exchange Server? Then OfficeCalendar is the solution you've been searching for.
