Outlook marking pop3 messages as read

[Andy D]

I have a user here who is using Exchange as his primary account and has an
additional pop3 account configured.
His primary Exchange account works as normal however; his pop account marks
all his messages read as soon
as they come in. Preview pane is turned off so its not that. Any ideas as
to why this is happening?

Thanks in advance.

I suspect he has an add-in that's scanning the messages, thereby opening
them and marking them read.
