A user has a set filter, not to show already read mails in outlook. The filter is mandatory for the user. The user also can access the mailbox using his blackberry (the BES is at the mercy of the mobile provider, and it connects to my Exchange using sPOP3)
When the BB phone connects, the emails are automatically marked as "read" which of course means the user will never see them in the Outlook inbox.
The question is how I can prevent this marking as read, so no email is missed in Outlook, without access to the BES (and the provider refuses to make any changes there). A way to mark anything pulled out via POP as unread will also work for me of course. I couldn't find a setting in the BB phone itself to prevent marking everything as read.
Versions: Outlook 2007 / Exchange 2010
UPD: after opening up IMAP the issue is resolved. Thanks to everyone who responded
