Outlook for Windows 11 is a useful tool for keeping track of your emails, but sometimes it can get buggy for various reasons. For example, on Reddit, this user had an issue with Outlook. The new app version would not open at all in Windows 11.

In the post, the user is trying to enable Outlook’s newest version, only to freeze and become stuck. And it goes on for some time and then stops. When trying to reach support, the app says that something went wrong. And that an error is occurring.

Outlook reportedly had some issues in the past but it’s quite frustrating to see them persist on the newer version as well. Luckily, the user has quickly found a solution from another Reddit user, dealing with the same issue.

So if you have the same problem with Outlook, try this solution, and see if it works for you too.
