Had this problem before where I copied my .pst to another system and couldn't access the contacts, even though they appear. This is using my ISP email so it's for a POP server instead of an Exchange server. For some reason when I go to create a new message and select a contact I get the following error: "The address list could not be displayed. The contacts folder associated with this address list could not be opened." A search on google advises I need to remove the old address list from the address book. I see how to do this using the Exchange service but not POP. Anyone have any suggestions on how to resolve this? Thanks in advance.
