- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Attempting to access organizational or student applications via the Microsoft Access Panel.
- Observed behavior
- The access panel gets stuck on a loading screen and eventually returns the AADSTS900144 error, often accompanied by a 410 error, due to an outdated or invalid redirect URL.
Ensure you have your correct organization or student login credentials available, and clear your browser's cache to prevent it from automatically loading old or deprecated redirect links.
Bypass the Broken Intermediate Redirect Link
Navigate directly to your institution's main portal instead of using saved bookmarks or intermediate links that may have been deprecated.
Error AADSTS900144 typically occurs when the application is trying to use an invalid or deprecated Reply URL (redirect URI). By going directly to the official source, you can bypass the broken routing path.
Open your web browser and navigate directly to the official homepage of your university, school, or organization.
Find the primary login button for the student or employee portal on the homepage.
Enter your Microsoft 365 credentials. Once logged in, launch your required applications directly from this main dashboard.

Report the Invalid Redirect to Your IT Administrator
If direct access fails, the issue must be resolved on the backend by updating the Azure AD application configurations.
Stay Productive Offline with WPS Office
If Microsoft 365 portal access issues are delaying your tasks, switch to WPS Office. It is a powerful, lightweight suite that works offline, ensuring you stay productive even when cloud access panels are down.

- 2. Install WPS Office: Run the setup file and follow the on-screen instructions to install the productivity suite in minutes.
- 3. Open Your Documents: Launch WPS Office and easily open, edit, and save your existing Microsoft Office files with complete formatting support.

Frequently Asked Questions
