I had a very interesting problem today that I’ve never experienced before with Exchange 2003 and OWA.
Some users advised that when in OWA the mail shown is a month old and no new mail is shown in OWA newer than the previous month. All e-mail is visible and accessible in Outlook though.
I logged onto OWA using the user’s credentials and noted the same. I then saw that the view in OWA is set to messages (which should show all messages) as per below:
I then chose unread messages (which shows unread mail but not necessarily all or recent mail) as per below:
This showed all unread mail but not the results we wanted. I then chose messages again and all mail was shown as we expected it in the first place. All read, unread, most recent and old mail as per the Outlook client was visible.
This however is a quick fix and the first time that I’ve personally seen it. I’m sure with some more investigation there will be a patch or config that will resolve this.
