My company considers the autocomplete feature in OWA to be a security flaw. Management's concern is that an employee could inadvertantly send an email about one customer to another customer. I have disabled autocomplete in GPO and that takes care of Exchange/Outlook. However, I must figure out a way to disable autocomplete in OWA 2007. Is there any way to completely disable autocomplete in Exchange/OWA? The company would even be willing to upgrade to Exchange 2010 if it allowed me to disable autocomplete in OWA.
