I'm desperate for an answer. I've developed a database using Access 2003 in an Access 2002-2003 file format. The problem is that I have users who only use Office 2002...that's why I use an Access 2002-2003 file format so both Access 2002 and Access 2003 users can run the .mdb. Access 2003 users run the database fine, but Access 2002 users cannot. This is what I've been able to find out so far. I use Access 2003 to develop the database. In the References section of VBA, there is a reference to "Microsoft Outlook 11 Object Library" at c:\Program Files\Microsoft Office\Office 11\msoutl.olb. When I copy the .mdb over to an Access 2002 machine and check the references, the Access 2002 VBA references "Microsoft Outlook 10 Object Library" at c:\Program Files\Microsoft Office\Office 10\msoutl.olb. My question is, how do I setup the database in Access 2003 so that it can successfully run in Access 2002? thanks in advance for any help!
