Outage in Appointlet

Elevated Office 365 Latency

Minor
November 12, 2026 - Started about 21 hours ago

Incident Report

We are seeing slow responses and timeouts from Microsoft's calendar service (Microsoft Graph). This affects customers who have connected an Office 365 or Outlook calendar. For these customers, scheduling pages may be slow to show available times or may not show them at all, some bookings may fail, and calendar syncing may be delayed. Google Calendar and other integrations are not affected.This is an upstream issue with Microsoft. We have added server capacity so other scheduling pages stay responsive, and we are monitoring Microsoft's service closely. We will post an update as things change.Thank you for your patience and understanding.

Microsoft 365 calendar connections are recovering. Since about 11:45 UTC, most requests to Microsoft are succeeding again, and scheduling pages for Office 365 and Outlook calendars are showing available times much more reliably.Microsoft hasn't marked the issue as resolved yet (https://status.cloud.microsoft/), and a small share of requests are still slow or failing, so we're keeping a close eye on things. If a booking didn't go through earlier, please try again.We'll post a final update once everything has been stable for a while. Thanks for bearing with us.
