Our latest version of Kerio migration code adds two options to the XML file to deal with autocomplete contacts.
- Set the
     ‘migratesuggestedcontacts’ switch to FALSE if you don’t want to migrate
     them.
- If 'migratesuggestedcontacts’  is TRUE, the contact subfolder named in
     the migratesuggestedcontacts_o365foldername will be created (if it doesn’t
     exist) and those contacts added to the folder.
