The message error pops up every 5 minutes informing as follows:
"Unable to add to the server Junk E-mail Lists, you are over the size on the server. The Junk Email Filter on the server will be disabled until your Junk E-mail Lists have been reduced to the size allowed on the server.
Would you like to manage your Junk E-mail Lists now?
I don't have any addresses on the list, tried to disable it in OWA, no filtering rules set on the server.
It occurs almost everyone in the network.
Any ideas please?
It's occurring in Outlook 2003 and 2007. Mail server is Exchange 2003 SP2.
