I have an application that consists of 2 mdb files. db1 links to tables in db2. When I copied the databases to a new Windows 8 PC using Access 2013 (the version that comes with Office 365) I can't link to the external tables. I hit EXTERNAL tab but the External Data Manager Icon is grayed out and is unselectable. Is there some permission issue with Access 2013 and Windows 8 that I'm missing?
