Tip 1108: Add meeting requests to Calendar as Tentative

I have a user who is managing several calendars on her Outlook. When she sends a meeting request to the users, she can see the appointments updated on her screen in those respective calendars except for one. One shared calendar doesn't update until the user manually accepts it in his Outlook. How can I solve this?

Check the user's auto-accept settings in File, Options, Mail. Near the bottom of the dialog, in the Tracking section, is the option that tells Outlook how to process meeting requests.

You'll want to have Automatically process meeting requests and responses to meeting requests and polls checked so meeting requests are added to the calendar marked Tentative as they arrive. With it disabled, meetings are added to the calendar as Tentative only when the user selects the meeting in their Inbox.
