Outlook 2003.  I was updating a small (six person) distribution list (DL) and
got this message when I tried to save the DL:

This distribution list is too large to save on your network email server.  
Please remove some members or put some of the names into separate, smaller
distribution lists that can then be added to this one.

We just switched over to Exchange Server 2003.  Thus, our contacts and
distribution lists are being saved on the server.  This particular
distribution list is part of the Contacts folder in the Public Folders.  I
have gotten this error message for other similarly small DLs.  When I delete
the DL and then build it from scratch, I do not get the error.  I cannot
always do this however, so please help!

What do I need to do to eliminate this erroneous error message?  Thanks

P.S.  When I delete
