I'm trying to think of a way to create a maintenance query to run regularly to find records that share the same email address. We want to review records that are for different people but sharing the same email, and also find duplicates where it's actually the same person (duplicate tools don't seem very good at finding these). I just can't think of a way to do it, other than pulling all the records out into excel and identifying them that way. Does anyone know how to do it?
