is there a limit of members of DL in Outlook contacts? We are using
Outlook 2003. I thought there is a page space restriction. How about
Outlook 2007? With limit how to check the free/used space?

I think Contacts will use mailbox size and there is no limit itself.
The limit if any will be based on mailbox limit, right?

Since you mention "mailbox", I'm assuming you're using Exchange. See this:
