We've got a mixed fleet of Outlook 2003 and Outlook 2007 users both accessing a single Exchange 2003 server. In recent weeks we have received numerous reports of Outlook 2003 users freezing whilst viewing an email in the reading pane.
We have built identical PC images - one with Outlook 2003 and another with Outlook 2007. We log on as an affected user on both PC's and randomly pick an email. The Outlook 2003 PC appears to freeze up with an hourglass & a blank reading pane for anywhere up to 10 minutes, whilst the exact same message viewed on Outlook 2007 displays immediately.
Anyone come across a similar issue? There are loads of forum posts referring to Outlook 2003 freezing when storing in a PST file, but that's not the case here - both are running Outlook in online (i.e. NOT cached) mode direct to the exchange server.
Any help is greatly appreciated!
