MapPoint has a limit of 10,000 records that can be mapped. Any record over this amount will not be seen as a pushpin, tack, etc. on the map.

Note: This is why all of Florida may be mapped but no push pins are in Georgia or South Carolina.

Workaround: Create queries of less than 10,000 records and map each query separately.

This is a limitation of Microsoft MapPoint. It is a 3rd Party Product and any changes made to the program can only be made by Microsoft. Contact contact Microsoft Support for further assistance.
