Fix Can't open Public Folder - Cannot expand the folder - Microsoft Exchange is not available - Exchange 2010

If you try to expand a public folder in Outlook and you receive the following error:

Fix Can't open Public Folder - Cannot expand the folder - Microsoft Exchange is not available

"Cannot expand the folder. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance."

or this message when trying to open open an address book from the public folder:

"The address list cannot be displayed. The Contacts folder associated with this address list could not be opened; it may have been moved or deleted, or you do not have permissions. For information on how to remove this folder from the Outlook Address Book, see Microsoft Outlook Help."Cannot expand the folder. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance

You will not receive any errors if you view the public folders through OWA, which makes the problem even more confusing.

Resolution: Start the "Microsoft Exchange RPC Client Access Service" on all your mailbox servers. In this case, both the mailbox servers shut off unexpectedly. When they came back online, that service was not started.

How to Fix - Cannot open the Outlook window. Invalid XML, the view cannot be loaded

After launching Outlook 2007 or 2010, you receive the following error message:

Cannot start Microsoft Outlook. Cannot open the Outlook window. Invalid XML, the view cannot be loaded.

To fix this error, run the following command from the Run box or from the path where Office is installed (For Office 2010, the path is: C:\Program Files\Microsoft Office\Office14):

Outlook.exe /ResetNavPane 

What does Outlook.exe /ResetNavPane do? It clears and regenerates the Navigation Pane for the current profile. Basically, it removes all shortcuts and favorite folders from the Navigation Pane. Not a big deal, as most users leave the default favorite folders in place, but just something to consider.
