Based on your description, it's likely that your Microsoft sign-in request is being routed through ADFS (Active Directory Federation Services), but the server is not configured to handle the request properly, likely due to missing or misconfigured protocol handlers.
After researching, here are some suggestions may be helpful to you:
- Check Device Registration
- Ask your IT administrator to verify that your device is registered and trusted in Azure AD or ADFS.
- They may need to re-register your device or remove and re-add it to the domain.
- Verify ADFS Configuration
If you have admin access:
- Go to the ADFS server and check the protocol handlers under:
/adfs/ls/
- Ensure that WS-Federation or SAML endpoints are enabled and properly configured
- Try Logging In via a Different Path
- Instead of using the default login route, try accessing Microsoft apps via:
- Clear Browser Cache and Cookies
- Sometimes cached credentials or cookies can interfere with ADFS routing.
- Clear your browser data and try again.
- Use a Company-Managed Device or VPN
- If your device is no longer recognized, try logging in from a company-managed device or while connected to your corporate VPN.
