We upgraded a Windows 7 machine to Windows 10 via the Media Creation Tool. Once the upgrade was finished Outlook wouldn’t run. We got the following error.

We uninstalled and re-installed the Office program but this didn’t solve the issue. We ran a repair from the “uninstall Program” but choosing “repair”. This time I start to check Office by opening Word and not Outlook. Word opened fine and so did all the rest of the Office suite. Outlook opened like it should.
