I am on a PC, using IE 8.0, and Outlook 2007. I have imported my Comcast address book into my Outlook Contacts folder successfully. To assign the contacts folder as my address book, I know I must click "Show this folder as an email address book" in the Contacts Properties window, it is checked but it is greyed out. (As a matter of fact, many of the options within the tabs on this window are greyed out.) I have re-created my profile twice and have checked the pst file for corruption by running scanpst and it was repaired. Once it was repaired, I recreated my profile one last time. Any ideas to help?
