Microsoft Bookings: sovereignty score and 8 European alternatives

Microsoft Bookings is an appointment scheduling app within Microsoft 365. It gives organisations a web booking page where customers can book appointments, and it is also available as an app in Outlook and Microsoft Teams. Staff publish personal or shared booking pages, define services and availability, and send email and SMS notifications. Bookings is included in Microsoft 365 subscriptions that contain it and is used through a browser or the Outlook and Teams clients.

Microsoft is headquartered in Redmond, Washington, in the United States, and is therefore subject to US legal jurisdiction, whatever the storage location of the data. Microsoft's documentation states that Bookings data is stored within Microsoft 365 and Exchange Online. For EU and EFTA customers, Microsoft offers the EU Data Boundary, which helps keep customer data in the region. The page consulted does not name Bookings explicitly, so the storage location for each tenant should be confirmed contractually. Bookings is proprietary software, not open source. For a European organisation, the question is mainly whether the wider Microsoft 365 contract and its data residency commitments are acceptable.

Why digital sovereignty matters with Microsoft Bookings

Microsoft Bookings is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Microsoft Bookings hosts data in US, EU. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Microsoft Bookings is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Microsoft Bookings together with your other vendors and gives a total score, a heatmap and the main risk drivers.
