PST File size limitation?

Hi folks,
I am creating an Outlook addin which adds MailItems to a MAPI Folder (PST
file). While I was volume testing, I came up against what looks like a
limitation in the number of items you can add to a folder on my PC (around
14000 nearly empty items).
Does this limitation apply across the board (i.e. is it part of MAPI)? Is it
documented somewhere? I'd like to be able to take evasive action before my
addin attempts to go over this limit.
Any help is really appreciated.
Cheers,
Ben
 
Any folder can only hold 16K items using small tables and 64K items using
large tables. Large tables were introduced in Outlook 98.

Thanks Ken.
Does 16K/64K refer to the size of one item or to the size of the whole
folder full of items?
