I’ve been having a problem with viewing “alerts” received from Sharepoint-2007 – with Outlook 2007 showing a blank preview pane, and a messagebox on double-click – simply stating “Cannot Open Item”.
It’s a Microsoft Exchange 2003 issue :
|•||You have a mailbox on a server that is running Microsoft Exchange Server 2003.|
|•||You use Microsoft Office SharePoint Server 2007 to send a notification message to the mailbox.|
|•||You try to open the SharePoint Server 2007 notification message in Microsoft Office Outlook 2007.|
|•||Outlook 2007 is running in Cached Exchange Mode.|
In this scenario, you cannot open the notification message in Outlook 2007.
There is a Microsoft hotfix – for Exchange Server 2003 >
Turning OFF “cached” mode for Exchange 2003 fixes the problem ! My laptop is configured for cached Exchange Mode – as the SDM Exchange Server is located in Adelaide (about 800 km away).
There’s a great post from Kathy Hughes re: Cached Exchange Mode – which fixed my laptop, but made it run rather slow. I think I’ll cope with the “cannot open item” message box – until the Exchange server hotfix has been applied.
