We're currently using Exchange 2003 and EV 6.0.
I tried the tech note, however we have this registry key already in place.
My suspicions lie with the fact the user has not used the Full Outlook Client and only uses OWA I think that a basket hasn't been created for the user aside from the OWA basket which is called evowa-vs1.
I can't see a basket \ folder created for a restore\shopping session for the user under the shopping folder in EV.
Any more ideas?
