Hey there!
I'm sorry that you are facing this issue.
HTTP 503 error indicates that the server is temporarily unavailable or experiencing a high load. X-
Unexpected end of JSON input suggests that the server returned an incomplete or empty response, preventing the client from processing it properly.
It looks like a temporary issue in the Exchange Online infrastructure or a transient outage affecting mailbox access.
Recommended Troubleshooting Steps:
Retry in InPrivate/Incognito Mode – Opens a clean session, bypassing cached data or cookies that might be causing session corruption.
Check Microsoft 365 Service Health – Visit the Microsoft 365 Service Health Dashboard
to verify if there's an active outage affecting Exchange Online or OWA.
Clear Browser Cache and Cookies. Remove stored data for Microsoft domains to refresh your authentication and session information. Press Ctrl+alt+Del in the Browser and delete cache and cookies.
Try an Alternate Browser or Device. Helps determine if the issue is specific to one browser profile or local system configuration.
Verify Network Stability. Ensure your internet connection is steady and not restricted by a firewall/proxy/Antivirus.
