One of our public address books has multiple groups defined. From Outlook, if you double click on a contact in a group, it says "Could not find Contact... It may have been deleted or moved..."
The same contact with the same email address is listed in the address book by company name, and you can double click on it to open it. If I remove and re-add the contact to the group, then I can double click on it in the group, but there are just too many groups and contacts to make this a practical solution. This happens from any Outlook application signed in as any user on our network, and also from Outlook Web Access. Does anyone have any idea how to solve this?
