I have a client with a problem using Outlook 2003, SP3.

They tell me that, suddenly, for seemingly no reason, they have
complete duplicate sets of folders/boxes in Outlook. They say that
some messages coming in go to one set, some to the other, and some to
both.

They also say that people are telling them they are sending emails,
but they are not receiving them.

Any suggestions?

Thanks,

Tim
