Your Excel contains more than 65,600 contacts and not all contacts have been imported during the process. The reason for this is because Excel 2003 and all previous versions have a limit on the number of rows in your file. The maximum is 65,536 rows. If you want to import more contacts, you can do this by importing a different file format, such as a CVS of a TXT file. Or you could split the file into two files.
