Exchange 2003 distribution list error.

I have a contacts folder located in public folders in exchange and in one of these contact folders there are over 3500 contacts and not sure how many distribution lists, in one of the distribution lists I got locked out, somebody was updating it and now I can not get into it I keep getting the error;

"Can't open this item. There is not enough memory available on the Microsoft Exchange Server computer to perform the operation. Contact your system administrator”

I have looked at this article and want to know has anyone else seen this problem before and fixed it another way?  This KB from microsoft says

"This problem may occur if the size of the distribution list in Outlook Web Access exceeds the total size of the contacts that are stored in Microsoft Exchange Server 2003. Exchange Server 2003 has a limit on the number of contacts that can be added to a distribution list. This limit is not fixed. Instead, this limit is based on the total size of the contacts that are stored in Exchange Server 2003"

Well that's great but it makes no sense because no way can there be more contacts in this distribution list then what's in whole exchange, maybe there are 200 contacts in the distribution list and in our exchange server we have thousand upon thousands of contacts.

I also looked at this article,, but I don't get that error so...

First off, do you allow your users to add members to a DL from within Outlook or OWA? Secondly, where do you get this error? From within Outlook? When in ADUC? When you attempt to get into the property pages? From the article it seems as thought this problem happens when you use Outlook to edit a DL. Go into ADUC and go to Properties --> Security for the DL. Match it up with another group that works and make the necessary changes.

Yes the error was within outlook, found the problem.  There was an unresolved email address within that Distribution List, and for some reason within outlook I was getting this error so what I did was I logged in trough web access and deleted the conflicted user and it all started to work ok.  I read that Outlook does not care about such errors and would ignore resolving the no email part and yet it seems like it was the other way around in my case.
Glad you found the solution.
