Outlook gives an Unexpected Error when emailing a group contact
Last Updated 3 months ago

This error is caused by sending an email to a group contact, selected from the locally stored Contact Suggestions List, that differs from the server.  To fix this error, you must hide the group contact from the Contact Suggestions List following these steps:

1. In a new email, start typing the group in a To, Cc, or Bcc box until you see the group name.
2.    Select the X to the right of the name to hide the group.
3.    Locate the group in your contacts to send to the group.

After approximately 24 hours, the refreshed group contact will be unhidden from the Contact Suggestions List.
