I developed an Access application that used OLE MapPoint2001 Maps in both forms and reports. The map quality was very good, same as a copy and past. After upgrading to MapPoint2002 the quality of the OLEs are so poor it has rendered MapPoint2002 maps unusable.

Answer:

I suspect this has to do with the fact that MapPoint 2001 used bitmaps as its default OLE embed format, and that MapPoint 2002 uses metafiles instead. I've seen a similar case where somebody resized the MapPoint OLE object - the bitmap made sure it resized proportionally so it didn't distort but the metafile didn't which resulted in distorted graphics. So it wasn't that the MapPoint 2002 image was of worse quality, but the target container distorted it.

I assume you can tell MapPoint 2002 to embed bitmaps like MapPoint 2001 - similar to using the Paste Special option through the UI (instead of just using Paste). Or if it is a disproportional sizing issue, you should update your application so it doesn't distort the metafile image.
