Fixes for the Outlook Not Implemented Error

  • Next, you just need to rename it. You can write Outlook.srs.old.
  • Now, simply restart Outlook. The new SRS file will be formed.
  • Now, see if Send/Receive is usually working or not.

3. Turn off the Antivirus Application 

Although antivirus applications protect your system sometimes, they can interfere with the working of various other applications. They scan every incoming and outgoing email, which can interrupt their work. 

To verify if the antivirus is behind the Outlook error not implemented, you can disable the antivirus and see if the error still shows. 

4. Make a new Outlook Profile
