If the errors are all coming from your Microsoft Office Outlook then the best way to fix it is to reinstall it. But when you do this, in case you installed additional plug-in, you may need to install it back after reinstalling Microsoft Office Outlook. To begin, click Start, Control Panel then open Add or Remove Programs.

Scroll down and select Microsoft Office then click Change. See image.

On the next screen, select Add or Remove Features and click Continue. See image.

In the Installation Options screen, click on the dropdown menu beside Microsoft Office Outlook and set it to Not Available. Click Continue. See image.

Wait for it to finish and then restart your computer. After this, repeat the first two steps until Installation Options screen. Here, click again on the dropdown menu beside Microsoft Office Outlook and select either “Run from My Computer” or “Run all from My Computer” and then click Continue. See image.

Restart your computer if it prompts you to reboot. See if the error appears again.
