With the latest Windows 10 upgrade rolled in, there is a pool of problems for the users that somehow remain unsolved. One such problem is nonfunctioning of Outlook which includes crashing after a Windows 10 Upgrade. If you are also stuck in this situation then perform the following steps.
Method 1: Disable the Add-ins
Method 2: Change File Permissions
Another reason for the occurrence of this problem is the corruption of data due to the upgrade. The error might inform you that it cannot open the files because it did not have any permission yet.
Method 3: Open Outlook in Safe Mode
Method 4: Clean Installation of Windows
If your system checker is unable to find the error files then you can also try performing a clean installation of Windows. Before doing that, ensure proper backup of your data and important files so that they are not deleted during the process. You can try reinstalling outlook in case none of the above solutions work for you.
Method 5: Reverting back to a Previous Version (Latest Fix- 16th July 2020)
Another workaround that we found for both cases of Outlook not working (including crashing and not initializing) was to revert to a previous build. If the current version isn’t working for you, then reverting to a previous version will definitely do the trick. The twist here is to find the latest stable Outlook version that you can revert back to. You can check third-party websites like Slipstick Outlook version History or Office 365 official version history. Once you identify the version number, you can use the command prompt beneath to revert back to it. Make sure to restart your computer completely before opening Outlook again. You might be required to enter your credentials again but other than that, you are good to go.
