We had several problems with suggested email addresses (auto-complete) in Outlook 2010. We are thinking, whether it is possible to disable this feature for every Outlook for every user. I know how to disable auto-complete (auto suggestion of email address) list in Outlook 2010 for one user. Is there any option how to disable this option for whole environment Exchange 2010 (for every user)? Some policy settings, script, program... Thank you in advance
