This is copied from The Help Section of Outlook 2007:
The maximum number of names that you can include in a distribution list
depends on the size of the contact files (for each contact) themselves.
There
are no hard and fast rules but in general, a distribution list can contain
between 50-70 names and e-mail addresses. A maximum number of e-mail
addressees, with minimum contact file size, is approximately 125, and this
can include other distribution lists.
For more information see the Knowledge Base article on the maximum size
for
distribution lists.
I just wish to know how I can reduce the file size and so increase the
number of entried in my DL.

I find that I can only get about 20 names in a distribution list. I
understand that the number depends on the file size of each entry. How
can I
find the file size and reduce it? (Simple language please!)
