First thing to try is to run ScanPST.EXE on your PST file to see if it's
damaged

I'm using M/S Outlook 2000 V. 9.0.0.2711

I've been having no trouble for the past 3 years or so but now when I try
to
delete a message from my inbox I get a message that reads "The messaging
interface has returned an unknown error. If the problem persists, restart
Outlook."

Restarting Outlook does not solve the problem nor does rebooting the
computer. I've run my virus scan but nothing came up.

What should I do now?
