A friend, at work, has a folder contacts (with his personal contacts) in his local *.pst folder, When he writes a new message, whet he click on To.. it opens only the company's contacts. Also, i have noticed that when I click properties on his local folder, go to Outlook Addreess Book, the "Name of this address book" checkbox is unchecked and disabled. How can I repair this, so he can use his personal contacts folder?
Problem solved: (As I mentioned this is for Office Outlook 2003)
As for the main symptom, you can manually set the address books that are used for name checking and their order of precedence.
In Outlook 2007: Tools -> Address Book -> Tools -> Options
There, you can add address lists to the name checking process.
