Love this forum! It orginally helped me build a database to manage customers back in 2002 (using Access 2002). Becuase of our slow server, I was forced to spilt the database and it's been great for years (some glitches). Recently one of the users upgraded to Access 2003. When he sync's to the master file, the master has problems. "...contains a missing or broken reference to the file 'OWC10.DLL' version 1.1" I reviewed the references and it's looking for Microsoft Outlook 11, instead of 10. When other users sync, everyone now inherits this problem. Do you have any ideas for a solution so I don't have to fix reference problems? All users will eventually be on Access 2003 so having him stop using it would only be a temporary solution. Is there a patch or upgrade to fix this problem? Any help? thanks in advance....
