- Product
- Outlook on the web
- Device & OS
- not provided
- Scenario
- Attempting to access, read, or manage emails and calendar invitations via a web browser.
- Observed behavior
- The Outlook web interface constantly refreshes and reloads on its own, making it impossible to click on, open, or view messages and calendar events.
Ensure your internet connection is stable and verify if other Microsoft 365 web services are loading properly before modifying your browser settings.
Use Incognito Mode and Clear Browser Data
Using a private browsing window helps determine if corrupted cached data or installed browser extensions are causing the continuous reload loop.
Browser extensions like ad blockers, as well as corrupted site cookies, frequently interfere with the web scripts required to load Outlook properly.
Launch your web browser and open a new InPrivate window (Microsoft Edge) or Incognito window (Google Chrome), then navigate to Outlook on the web and log in.
Attempt to open an email message or create a calendar invite. If the site functions normally without reloading, the issue is tied to your standard browsing profile.
Return to your normal browser window, go to the extensions management page, and disable all active extensions. Refresh Outlook to see if it works, then turn them on one by one to find the conflicting extension.
Navigate to your browser's privacy and security settings. Select the option to clear browsing data, ensuring that cookies and cached files specifically for Outlook and Microsoft 365 are checked and deleted.
Try an Alternative Browser or Network
Network restrictions or outdated browser versions can prevent Outlook from establishing a stable connection with Exchange servers.
Check Microsoft 365 Service Health
If the reloading persists across different devices and networks, the problem may be an outage on Microsoft's servers.
