We have an Exchange 2003 cluster in wich we have limited the number of recipients in the past. We deleted it but it's still affecting our service. I have moved the services to the other node (it's an active/pasive cluster) so i guess i have restarted with this procedure the "Microsoft Exchange Information Store service" as is required to limit it (http://technet.microsoft.com/en-us/library/aa996677(v=exchg.80).aspx). anyone have any idea why the limitation is not deleted?
