I'm running Exchange Server 5.5 Enterprise on an NT4.0 Server.
The clients are using Outlook 2000 on Win 98 SE workstations.
Mail flows to and from our ISP via the IMC no problem but as soon as
somebody tries to send an attachment with their mail the outbound message
queue seems to stop sending and mail just bottles up.
I've applied Service Pack 4 but the problem is still there.
Can anyone please help........................much appreciated.
