If when you start Entourage 2008 for Mac or Entourage 2004 for Mac and you notice that All calendar, contacts, and email data is missing, then this article may interest you.
You may ecncounter this issue, if the Microsoft User Data folder (MUD) or the identity that contains the most recent data was moved from its expected location. Entourage must have the Microsoft User Data in the Documents folder. And the Documents folder must not be renamed.
To resolve this issue, Microsoft KB970509 outlines methods that is appropriate for your version of Mac OS X.
However, this problem cannot be resolved if the following conditions are true:
– The Microsoft User Data folder was moved to the Trash, and the Trash was emptied.
– You do not have an archive or a backup of the MUD/identity/database.
– You do not use Time Machine.
