Exchange 2003, edit distribution list on exchange mailbox and get "memory error"

I'm running Exchange 2003 SP2.  When a user tries to open up a large (106 addresses) distribution list from their contacts on the exchange server via Outlook 2003, they receive "Can't open this item.  There is not enough memory available on the Exchange Server computer to complete this operation.  Please contact your administrator."

We've researched this and found it could be an issue pre SP2 if the Dist list was opened and edited w/ the web client, but SP2 contained a correction for that.  I've added a GB more RAM, same problem.  If I copy/move/export the contacts to a PST, I can open and edit them fine.  Move them back, and same error.

The "not enough memory" message doesn't always mean what it says.
How much RAM did you add to the server, because Exchange cannot really cope with more than 2gb.

There is a limit on the size of a personal distribution list when used with Exchange, I am wondering if you have hit that limit.

Try breaking down the list in to nested sub lists - so that the list is made up of two sub lists, each with 50 odd members.

I have a total of 2gb in the server.  I will have the user change the lists and see if that works.
