I recently started having issues with Microsoft Outlook on all of my computers. I joined a company that uses 365, but my machines were all running Office 2019. I didn't think that would be a big deal but lord was it. Just wouldn't open at all, and going through the Windows control panel was futile. Uninstalling and deleting the AppData and Microsoft folders didn't help either; there were some configs still hidden. So, I decided to kill it with fire and do a fresh install. Boy did I forget how much work it takes to get Windows up and running again.
