Last weekend we've switched from a 2000 SBS server to a 2003 standard server.
To save time, we haven't installed our client from scratch.  Instead we took
our clients out of the old domain into a temporary workgroup and afterwards
put them in the new domain.

For e-mail, we exported everyone's mailbox to a pst on the old domain, and
imported these files in the new domain.  On the client we pointed to the new
Exchange, which works, save for one problem.  The personal contacts are
accessible in the folderlisting in Outlook, and the data is intact.  However,
when I write a new e-mail, click on To: and try to open the personal contacts
list from there, I get a message that the address book can't be opened, and
that it has either been moved or removed, or that I do not have the necessary
permissions to access it.

I'm aware that I can create a new address book and copy all contacts to that
one, but I cannot remove the original one.

Is there a way to use the original personal address book again?

Thanks in advance for your help!
