I have recently transferred to my new computer. All outlook files and
settings are working well, except when I try and acces the contacts list from
a new email. I click on "To" or "CC' and the meassage "The address list could
not be displayed. The Contacts list associated with the address list could
not be opened it may have been removed or deleted......"
The contacts list is accessable through Contacts and this function worked
previously on my old computer with the same setup.
Hard to know what you did wrong, since you did not tell us what you did.
If I were you, I'd reconfigure your Outlook Address book.
I'll assume you know how.
You also did not provide your Outlook version.
