I am trying to disable our users from being able to resolve contacts that are in their address book when composing a message. When I try on my account to disable the "Contacts" folder from showing as an Address Book under properties -> outlook address book, the option is checked and greyed out. How can I disable this? Is there a way that I can do that for my whole organization?

I am running Exchange 2013 with outlook 2013 running under cached mode. The email accounts are added through autodiscovery.

Hi,

sorry i don't understand you clearly, could you attach a printscreen? Thank you!

regards,

Csaba

Go to people hub, on the left side, right click on "Contacts" and select properties. In the dialog that comes up there is a tab called "Outlook Address Book" Click on that. There is a setting there which is the one that I am saying is greyed out and I cannot disable. It is "Show this fodler as an e-mail address book"
