For some reason your Outlook shortcuts will dissapear or any shared items through public folders will no longer appear within your Outlook profile.  We’ve only seen this issue in Outlook 2007 but it may happen in Outlook 2003 as well.  You have two options to fix this issue:

1.    You can create a new email profile. This will reset everything you’ve customized within Outlook so it is a last resort option.  The next option is your best bet

2.    Navigate to the folder in which Outlook stores its settings. In Windows XP it defaults to:

o    C:\Documents and Settings\\Application Data\Microsoft\Outlook

o    In this folder you will find a file called Outlook.xml

o    Exit Outlook completely, check taskmanager to ensure outlook.exe is not running

o    Rename the file to Outlook.xml.old

o    Open Outlook and you will notice all of your favorites and calendars are gone, you will need to re-setup your shared calendars and contacts
