If your team stores its project schedules, conferences, or vacations on a Share Point calendar, you can view the team calendar simultaneously with your personal calendar and check for conflicts.
These can include Internet connectivity issues, inaccurate account information, glitches with the type of view you're using, and incorrect Auto Archive and Delegate Access settings.
The most common reason meeting invites are not populating in your Outlook calendars is a problematic Internet connection.
You can view a calendar from a Share Point site side-by-side with an Outlook calendar, view an overlay of the calendars as if they were one single calendar, and even copy events among the calendars.
When you connect a Share Point calendar to Outlook 2007, it appears under Other Calendars with your calendar folders.
If you've noticed missing calendar appointments (e.g., lost meetings, delegate issues), or meeting updates from someone other than the original organizer, you're not alone.
