Fix “Not Implemented” Error in Microsoft Outlook on Windows

Outlook is a popular email client developed by Microsoft that provides a variety of features, including email management, calendar scheduling, and task management. However, despite its usefulness, it is not uncommon for users to experience errors when using Outlook, such as the “Not Implemented” error.

How to Fix Outlook Error “Not Implemented”?

The “Not Implemented” error can occur when a user tries to perform a particular action in Outlook, such as sending an email, replying to an email, or creating a new contact. This error message indicates that the action you are trying to perform is not support by Outlook or that there is a problem with the program.

If the PST file gets corrupted, you may encounter a “Not Implemented” error. To repair corrupt PST files, you can use Outlook’s in-built Scanpst.exe tool (also known as Inbox Repair Tool), or an Outlook PST Repair Tool such as Bitrecover Outlook PST Repair Tool .

There are several reasons why the “Not Implemented” error might occur. One of the most common causes is a corrupted installation of Outlook. If this is the case, you can try repairing the installation by going to the Control Panel, selecting Programs and Features, and then selecting Microsoft Office. From there, you can choose the Repair option and follow the prompts to repair the installation.

What are the Other Causes for Outlook Error Not Implemented?

Another possible cause of the “Not Implemented” error is a problem with Outlook add-ins. Add-ins are additional features that can be install to enhance the functionality of Outlook. However, some add-ins can conflict with other software or cause issues with Outlook. To fix this problem, you can disable any third-party add-ins by going to the File menu in Outlook, selecting Options, and then clicking on Add-ins. From there, you can select any add-ins you want to disable and click on the Disable button.

Additionally, a corrupted Outlook profile can also cause the “Not Implemented” error. A profile is a set of settings that Outlook uses to connect to your email account, and if it becomes damaged, it can cause problems with the program. To fix this, you can create a new Outlook profile by going to the Control Panel, selecting Mail, and then clicking on the Show Profiles button. From there, you can create a new profile and set it as the default profile.

In some cases, the “Not Implemented” error can also be caused by issues with your computer’s registry. The registry is a database that stores important information about your system, and if it becomes corrupted or damaged, it can cause problems with programs like Outlook. To fix this, you can use a registry cleaner tool to scan and repair any issues with your computer’s registry.
