Thank you for your question.
The University of Indiana Computer Center notes the following
regarding number of contacts in Outlook 2000:
Q: What is the maximum number of contacts that can be stored in the

form of a .pst file or "primary store" is shared between several
Outlook 2000 funtions as follows:
OL2000: (CW) Purpose and Capacity of Outlook Storage Facilities
"...Personal Folders Files Located on Your Computer
One or more .pst files can reside on each user's computer. A .pst can
be defined as your primary store or as a secondary store. A primary
store means that mail delivered to the Inbox in that file and all of
your other default Outlook folders, such as Calendar, Contacts,
Deleted Items, Journal, Notes, Sent Items, and Tasks reside there. A
.pst file can also be defined as a secondary store, which means you
can move items to that file, either manually or with Inbox Rules, from
your primary store.
Each .pst file can contain a maximum of 65,535 top level items, and a
maximum of 65,535 items in each folder. An item is a folder, message,
task, etc. Upon reaching 16,384 items, you are upgraded to a large
tables format, which increases the limit from 16,384 to 65,535. The
total file size of a .pst cannot exceed 2 Gigabytes (GB)..."
Consequently, the answer is it depends on how many saved email
messages, calendar items, notes and tasks you have as well as
contacts. The aggregate can not exceed the limits as Microsft notes
"outlook 2000" +maximum +"number of contacts"
