The error message "the name cannot be matched to a name in the address book" typically occurs when the user account is not associated with a mailbox or is hidden from the Global Address List. Additionally, it may happen if there are issues with Active Directory permissions or the Exchange Recipient Update Service. To resolve this issue, ensure that the user account is correctly configured and associated with a mailbox.
If you continue to experience problems, you may want to check the configuration of the user’s mailbox or consult your IT administrator for further assistance.
