message is read - symbol unread

[Karin Walisch]

hello,

system: MS Exchange 2003 SP-2, MS Outlook 2003 SP-2 with server store, no
cache mode
problem: a message which is read is shown in the list with symbol closed
envelope for unread. the subject of the message is shown as not bold (=read).
when I open the message again the symbol doesn´t change.

do I work with OWA (Outlook Web Access) the same message is shown ok -
symbol unread = envelope open

starting outlook.exe with /cleanviews = without success

what can be the reason?

thanks and best regards
Karin
