Today, when one of my customers pressed the “Send-Receive” button to check for new email messages using Microsoft Outlook (2010), suddenly he received the “Not implemented” error message on his screen. As a result of this error, the customer couldn't use Outlook to send or receive any messages. After some research on the installed programs, we discovered that two versions of MS Office were installed on the computer and the Outlook program settings probably were corrupted. So we applied the following solution to solve the “Not implemented” error:
