Microsoft Office 365 Authentication Issues
Incident Report for Interseller

Due to an unexpected issue with Microsoft OAuth, users using Interseller with Outlook 365 accounts were affected. This caused issues logging in and refreshing OAuth tokens with Microsoft. Because this was an outage with Outlook 365, we then ceased all API operations with Outlook using our service toggle. Services began to restore normally while Outlook 365 remained paused. Microsoft then restored service within several hours which also restored logging in with Microsoft and sending/syncing with Outlook accounts.
