What you’re seeing
- The new Outlook for Windows opens to a plain 'Something went wrong' page with a Retry button that does nothing useful.
- The spinning loader appears, then the error returns before the inbox ever shows.
- Outlook on the web works fine in a browser for the same account on the same PC.
- Restarting the computer, signing out of Windows or reopening the app gives the same result.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- The Microsoft Edge WebView2 runtime that the new Outlook depends on is missing, outdated or damaged.
- Cached account data or sign-in tokens stored by the app have become corrupted.
- A proxy, firewall or web filter blocks Microsoft cloud addresses the app needs to load mail.
- The account type isn't supported by the new Outlook, such as a mailbox on an on-premises Exchange server.
- Windows account broker components that handle work sign-ins are failing, which also affects other Microsoft apps.
Why it matters
For users who have been switched to the new Outlook, this error means no email, calendar or contacts in their normal app. They lose time hopping to a browser, miss meeting reminders and may not see urgent client messages. Because the message gives no detail, staff often reinstall or reset things themselves, which can make matters worse. Multiple users hitting the same error usually signals an underlying network or update problem that affects the whole office.

Frequently asked questions
Is our email lost?
No. The new Outlook is a window into your mailbox in Microsoft 365, so mail stays safe in the cloud even when the app won't load.
Can we go back to classic Outlook?
In many cases yes, depending on your licensing and any admin policies, though Microsoft is steadily moving businesses toward the new version.
Can AskTechGurus fix this remotely?
