I'm having trouble identifying the cause behind an inability to drag and drop emails between folders in OWA (Exchange 2010).
The problem PC is running fully up to date 32 bit Windows XP SP3 with IE8. When I try to drag and drop an email all I see is a black stop symbol. On another PC with the same spec, logged in with the same user account, I can drag and drop emails fine between folders in OWA.
I've tried clearing browser cache/history etc, resetting the browser to factory defaults, re-installing the browser, reducing security in the browser to absolute minimum, re-installing Java, Silverlight, S/MIME (although I'm sure it doesn't use these).
Can anyone suggest anything else, or provide helpful links? I've been looking at this for many hours without any progress. If I even just knew what component/tool/feature IE is using when it does/doesn't drag and drop I'd have somewhere to start...
TIA.
