It seems that ‘Document Access’ from Outlook Web Access (OWA) is no longer supported in Exchange/OWA 2010.
However, the way this element of ‘Discontinued Features and De-Emphasized Functionality’ is worded (“Can’t use…”) makes me think it is more of a known issue than a conscious decision they have made – where is the reasoning and/or alternative solution ? no mention…
Also, all of the configuration functionality for this feature still exists in Exchange 2010 Management Console.
Smells like they just didn’t get the Outlook Web App finished in time. I wonder if this will be in SP1 – it was a pretty neat feature after all – or will SP1 remove the configuration elements in the Management Console ?
