Hello, I'm Quinn and here to help!
If you can’t send or receive email in Outlook, the most common cause is full Microsoft cloud storage. Try to free up space by deleting large emails or emptying Junk/Deleted Items folders.
- Sign in to Outlook.com
- Go to Settings > General > Storage
- Free up space by deleting large emails, attachments, or emptying Deleted Items and Junk folders
- Refresh Outlook and test sending and receiving again
If your storage is not full and the issue persists:
- Press the Windows key, type Services in the search bar, and open the Services app.
- Scroll through the list and find GoogleUpdater (there may be multiple entries).
- Double-click each GoogleUpdater entry.
- Set the Startup type to Automatic.
- If the service is not running, click Start to launch it.
- Click OK to save your changes.
- Close the Services window.
- Restart your computer to apply the changes. See if this fixes the issue.
Also, ensure your account isn’t blocked and Outlook isn’t in Work Offline mode. For more troubleshooting steps and possible causes, see the official Microsoft support article:
