The behavior of that dialog is hard coded and can't be changed.

We have a user that is typing names in the To: line of her Outlook client,
and then uses the "Check Names" icon to resolve the name to an entry in the
Global Address List. Sometimes there might be as many as 50 or 75 matching
names, but it will only show about 20 or 30. What determines the number of
names returned by this tool, and is there any way to increase the default
number of results returned so that it is more comprehensive? She would like
to see all the matching results whenever she uses the "Check Names" feature.

Thanks,

AJ
