Connection Run-time error ‘3709' ★★★★★★★★★★★★★★★ David Musgrave10 April 20132 Share 0 0 It has been a long time since I shared run time error 3709 the connection cannot be used a Quick Tip for Visual Basic for Applications (VBA), but I have run time error 3709 the search key was not found had this one waiting for me to write up for a while.
