If you’re a business user and have a calendar that you would like to give people in your organization access to, you can do it through Microsoft Outlook.

NOTE: This will only make a copy of the contacts currently in your Calendar folder. It will not synchronize your public folder calendar list with your Calender folder. Unfortunately, there’s currently no way to do that in Outlook or Microsoft Exchange.

Procedure:

In Outlook, click Calendar.

Click Edit->Copy To Folder.

In the window that pops up, scroll down and click the plus sign next to Public Folders.

Click the plus sign next to All Folders.

Click the plus sign next to your organization’s domain name.

Click Public Folders to highlight it.

You can choose any folder, however you should probably rename your contact list so its easier to identify.

For this example will place a copy of the Calendar in a newly created Calendar subfolder called ABC
