Microsoft is experiencing a global outage affecting Outlook and/or Teams since Thursday, November 12, 2026, at around 6:25 PM (Paris time). The cause lies with Microsoft: Agendize services remain operational. However, depending on how your calendars are connected to Outlook, features that rely on Microsoft may be disrupted.
If your calendars are synchronized with Outlook (Office 365)
- Sign-in with a Microsoft account: users who sign in to Agendize with their Microsoft account (SSO) may be unable to sign in.
- Appointments sent to Outlook: appointments booked, modified or canceled in Agendize from November 12 until the service is restored may not appear in Outlook. Agendize automatically retries sending them, but if the outage lasts, some appointments may not be transmitted.
- Outlook busy times: the booking widget may no longer take them into account. Customers may therefore book slots when the staff member is busy in Outlook.
Your synchronizations should remain in place: you should not need to reconnect your calendars once Microsoft has restored the service.
If your Outlook calendars are connected via ICS subscription
- Outlook busy times: the booking widget may no longer take them into account. Customers may therefore book slots when the staff member is busy in Outlook.
Video conference appointments
Teams links can no longer be created. During the outage, each video conference appointment automatically receives a Jitsi link instead. The staff member and the customer join the meeting using this link, which is included in the appointment.
Our recommendations
- During and after the outage, rely on the schedule in the Agendize console rather than the Outlook calendar. It contains all appointments, including those that were not sent to Outlook.
- During and after the outage, you can send your staff members a notification with their appointments for the day from the Notifications menu. This way, they have their up-to-date schedule without going through Outlook.
- If needed, block the slots when your staff members are unavailable directly in Agendize, so that customers cannot book them.
- Let your staff members know that video conference appointments created during the outage have a Jitsi link instead of a Teams link.
- Once Microsoft has restored the service, check the appointments booked, modified or canceled since November 12. Make sure they appear correctly in Outlook and do not overlap with a busy time. In case of a conflict, offer the customer another slot.
