When I insert a new appointment into my Outlook 2007 (client: Windows Vista, server: Exchange 2003 on SBS 2003) and after closing Outlook and then opening it again the item is not there any longer. I can see all the items that were entered in the Calendar before.
In OWA I can only see that the days with appointments are marked bold, but cannot see any appointments there. When I'm trying to insert an appointment using OWA after hitting Save & Close button I get an pop up window warning that The action can't be performed.
Your help is highly appreciated.
