I am a home user with a single computer using Outlook 2007. I have dealings with an organisation that is somehow able to add appointments to my calendar. I have not given permission for this and can't see how to prevent it. When I right click on Calendar in the navigation pane I do not get "Change Sharing Permissions", as the Help page suggests I should, but only "Open in New Window" and "Navigation Pane Options".



Can someone please explain step by step and in words of one syllable how I can control access to my calendar and prevent others from adding to it. Any help will be greatly appreciated.

It sounds like your Outlook may be set to automatically accept meeting requests. Check the Resource Scheduling settings:

1. In Outlook, click on Tools.
2. Click Options.
3. Under the Preferences tab, click the Calendar Options button.
4. Click the Resource Scheduling button.
5. Make sure "Automatically accept meeting requests and process cancellations" isn't checked.

Hope this helps.

Thanks but, no, it's not checked.
