Actually, the error is *given* by the exchange server, so likely your Outlook 2000 clients with this problem are on an Exchange network.
There are at least a dozen scenarios where something like this could "suddenly happen". For example: If the network administrators changed the connection or relay configuration of the exchange server, and the outlook client lists the exchange server as the primary delivery method. Outlook is really crappy about defaulting to lower delivery methods. Have your clients go to their menu bar, select TOOLS --> SERVICES, click on the DELIVERY tab, and ensure that the Internet E-mail delivery method is moved to the top so it is selected first. Also, it should be brought to the attention of their exchange administrator. -- Michael E. Cummins > >We have recently just been getting this error on a number of users > >internet email.
