Sent Mail appears as unread

Hello,

We have a Domino 5.0.8 and a Domino 6.0.1 Server. People use their Mailfile on the 5.0.8 Server with their Notes Client. We replicate the Mailfile with the Domino 6.0.1 Server for Web Access with iNotes.

Then a user sends a mail from his Notesclient the mail appears correctly as read. If you open the Mailfile on the Domino 5.0.8 Server with the same Notesclient and user after it is replicated with the Domino 6.0.1 Server the sended mail appears as unread.

Please help

Thanks

Alexander Scholz
