If this does not work with you, can you please provide more information about what Outlook you use?
Thanks Sigi In Outlook 2010 you must (or can) right click on the calendar in public folders and choose add to favorites.
When you click Calendar in the navigation pane, you'll see a list of My Calendars (those in your mailbox) and Other Calendars (from Windows Share Point Services—WSS—sites or other Exchange users' mailbox Calendar folders that you've viewed).
The trick to adding a public folder calendar to the Other Calendars list is to switch to the folder list and drag the calendar folder to your Public Folder\Favorites area.
The problem is, running this also kills all linked shared calendars, shortcuts and favorites.
The /Reset Nav Pane switch seems to delete the xml file and likely does other things to the mailbox or registry.
How can I add a public folder calendar to the list of Other Calendars in Microsoft Office Outlook 2003 so that I can see it side-by-side with my personal mailbox Calendar folder?
The ability to display multiple calendars side-by-side is one of the most useful new features in Outlook 2003.To do this, right-click on the calendar and choose ‘Add to Favorites’ First, locate the calendar in a Public Folder, right-click on it and select Add to Favorites and then click the Add button to add it to your Public Folders Favorites. Requests for authorization to add a Public Folder need to go through your IT Support Staff.The liaison would then fill out and submit a public folder request form .You right click the Public folder and select “Add to Favorites” , it prompts for a name and then appears to add it, but it does not actually appear in the list.The common answer to this issue is that the file in “C:\Users\username\App Data\Roaming\Microsoft\Outlook” is corrupt and start Outlook with the /Reset Nav Pane switch.One of the important features of an Exchange mail system like Office 365 is the ability to share a calendar and contacts. But that kind of “shared mailbox” can’t be seen on mobile devices.
