Did you have the Small Business Customer Manager installed on the old hard
drive because the problem contacts are looking for the Datagrid control
which is included in msdatgrd.ocx. To get around this Export the Contacts
folder to an Excel format and then re-import but re-import to a sub folder
of type Contacts first. Once you are satisfied the Contacts are all present
and correct delete the Contacts in the Main Contact folder and then drag and
drop from the sub folder. If this doesn't work properly you may have to use
a utility called omsgclas.doc which is a word document that changes the
message class of Outlook items. The message class of a standard Contact
item is IPM.Contact. More on the message class utility here:
