When trying to send a new email or reply to one, we may receive an error message that says “Not Implemented.” Although this issue is very frustrating, especially if you are required to send a work email immediately, there are things we can do to resolve it. In this post, we will see what to do when you encounter a Not Implemented error in Outlook.

If you see a Not Implemented error in Outlook, follow the solutions mentioned below.

Let us talk about them in detail.
1] Repair or Microsoft 365 or Office Installation
If you receive this error, the first thing you want to do is repair your Microsoft 365 or Office installation. To do the same, you need to follow the steps mentioned below.

2] Start Outlook in Safe Mode
Outlook Safe Mode is a diagnostic mode that disables add-ins, extensions, and customizations.
To do this, open the Riu box, type outlook /safe, and hit Enter. If it runs fine, you may want to check the installed add-ins. Disable some Outlook add-ins and see if that helps you.
Click File menu > Options > Add-ins > Go button beside Manage: Com-in Add.
Try to identify the offending add-on and disable it. Restart Outlook and try.
3] Reset the Outlook SRS file
The Outlook srs file contains the settings that you set using the CTRL+ALT+S Send/Receive Groups settings. To do this, close Outlook and navigate to the following folder:
C:\Users\%username%\AppData\Roaming\Microsoft\Outlook\
Delete the Outlook.srs file that you see. When Outlook restarts, the file will be automatically re-created.
