I recently started getting the following error when composing a message (new or in reply) in OL2000: "The item could not be saved because it has been changed by another user or in another window. Do you want to make a copy in the default folder for the item?" I think the problem started after I did a Detect and Repair operation on Outlook. I don't see anything in the MS Knowledge Base about this. BTW, Outlook is set up for Internet-only mail.

If upgrading Outlook to a new release is the answer, what do I need to know about the new Outlook email security options. I recall reading warnings about them.

Thanks for any help.
