We have identified an issue that is affecting Microsoft Outlook Calendar users and signups, which is preventing the ability to sign up or connect Microsoft Outlook Calendars to Reclaim accounts. Specifically, we've discovered an issue with the Microsoft Graph API where the main /me/calendars endpoint is returning an Internal Server Error (500). This issue is widespread for all services that integrate with Microsoft calendars and is not isolated to Reclaim. We and other companies have raised the issue up with Microsoft and are awaiting a resolution.
