ZOREAL Book

Alternatives to Microsoft Bookings

Microsoft Bookings is the appointment-scheduling app inside Microsoft 365, not a product sold on its own: a web-based booking page integrated with Outlook, in a personal shape (your own meeting types and a shareable link) and a shared shape (services, staff members and business hours), with email and SMS notifications. ZOREAL Book is the scheduling product inside ZOREAL Meet: a client defines the kinds of appointment people can book with them, gets a hosted page and a snippet for their own site, and a guest picks a free slot from a calendar that never overlaps the host’s real one, with a booking that ends in a call ending in a Meet room. This page sets the two side by side: how a booking is made, who the booker is shown to be, which calendar each reads, where the meeting happens, and what each costs.

Information last reviewed 11 September 2026. Compared: Microsoft Bookings (Personal and Shared Bookings inside Microsoft 365) with ZOREAL Book. The Teams meeting a Bookings appointment can create is compared with ZOREAL Meet on the Microsoft Teams page; Microsoft’s other products and its group revenue are out of scope.

Where ZOREAL Book and Microsoft Bookings differ

  • Where the booked call happens

    Each Bookings appointment booked as an online meeting creates a unique Teams meeting link, joinable by browser, app or phone dial-in, per Microsoft’s overview. In ZOREAL Book a confirmed booking with a Meet room location creates a ZOREAL Meet room, joined by link in the browser, where the host can require a presence check at two levels (ZOREAL Presence, ZOREAL Identity), each a full liveness capture and a face match against the document read at enrolment.

  • Who the booker is shown to be

    On a public Bookings page the customer is the email, phone and answers they typed; the alternative Microsoft offers is restricting the page to accounts of the organisation through a Microsoft Entra sign-in, which shows the booker holds a tenant account. On an open ZOREAL Book event type the guest confirms their address with a six-digit code before the booking is made, and the guest is not asked for a phone number. Who is in the call is what Meet’s own presence check proves, in the call.

  • Payments at booking

    Microsoft’s FAQ answers the payment question directly: "No, there’s no payment support in Bookings." A service can show a price for display. A priced ZOREAL Book event type sends the guest to Stripe Checkout on the host’s own Stripe account, with a ten-minute hold; paid is read back from Stripe, refunds are handled, and the booking asserts that the guest paid before the slot was held.

  • Calendar sources

    Bookings takes staff availability from the staff member’s Microsoft 365 calendar in Exchange Online and is "a cloud-only application", not supported in a federated or hybrid environment; no other calendar source is stated in the public materials we reviewed. ZOREAL Book’s calendars are local or connected Google calendars, read for busy time and written to with the booking; slots are computed live at booking time and a database exclusion constraint refuses a second booking over the same minutes for the same host.

AttributeZOREAL BookMicrosoft Bookings
How a booking is madeSlots are computed live at booking time from the host’s availability schedule, date overrides, public holidays, buffers, minimum notice and booking window, minus busy time from every connected calendar, and a database exclusion constraint refuses a second booking over the same minutes for the same host. A priced event type sends the guest to Stripe Checkout on the host’s own Stripe account, with a ten-minute hold. A confirmed booking with a Meet room location creates a ZOREAL Meet room; the guest gets a manage link and a calendar file, and the host’s connected calendar receives the event.A customer opens the published booking page (book.ms, a shared link or an iFrame embed), picks a service, a staff member (or "Anyone", assigned at random) and a time computed from business hours, the scheduling policy (time increments, lead time, maximum days in advance) and the staff member’s Outlook free/busy, and enters email, phone, address and notes plus custom fields; Bookings creates the appointment in a Bookings mailbox in Exchange and sends a confirmation with an ics attachment. "Bookings will only let one person book that time." (Shared Bookings FAQ; define your services; scheduling policies).
Identity of the person bookingOn an open event type the guest confirms their address with a six-digit code before the booking is made; the guest is not asked for a phone number. Who is in a call is what Meet’s own presence check proves, in the call.The email, phone and answers the customer typed on a public page, or a Microsoft Entra sign-in when the page is set to "Require a Microsoft 365 or Office 365 account from my organization to book", which restricts it to the tenant. A document, face or liveness check of the customer is not stated in the public materials we reviewed (Shared Bookings FAQ).
Calendar sourcesLocal calendars and connected Google calendars, for busy time and event writing: consent, sync, push, event writing, and blocks written to the account as busy events.The staff member’s Microsoft 365 calendar in Exchange Online, when events on the calendar are set to affect availability and the staff member shares free/busy; staff can be added by any email address without a Microsoft 365 account, with no calendar sync stated for them. "Bookings is a cloud-only application. It isn’t supported in a federated or hybrid environment." Google Calendar, iCloud or CalDAV as a source is not stated in the public materials we reviewed (Shared Bookings FAQ; overview).
Where the meeting happensA confirmed booking with a Meet room location creates a ZOREAL Meet room, joined by link in the browser; the guest gets a manage link and a calendar file, and the host’s connected calendar receives the event. In the room the host can require a presence check at two levels, ZOREAL Presence (a real, enrolled, live human is present) and ZOREAL Identity (the same plus the verified legal name), each a full liveness capture and a face match against the document read at enrolment. A booking that does not end in a call still lives on the same calendar as the calls.Each appointment booked as an online meeting creates a unique meeting link sent to attendees, joinable "via a web browser, phone dial-in, or the Skype or Teams application"; otherwise the location field carries the business address (overview; define your services).
Reminders and notificationsConfirmation, reschedule and cancel mails with a calendar file; the 24-hour and 1-hour reminders; approval, attendance confirmation, no-show and conflict handling.Email confirmation, email reminders and email follow-up to customers, staff members or both, at chosen times before and after the appointment, with multiple reminder messages allowed; SMS text notifications require a Teams Premium licence and a valid United States, Canada or United Kingdom phone number, with the customer opting in per booking (define your services; SMS notifications page).
PaymentsA priced event type sends the guest to Stripe Checkout on the host’s own Stripe account, with a ten-minute hold; paid is read back from Stripe and refunds are handled. A paid booking asserts that the guest paid before the slot was held for them, referenced to a Stripe payment on the host’s own account."No, there’s no payment support in Bookings." A service can carry a price for display, and "Price not set" hides any reference to cost (Shared Bookings FAQ; define your services).

IntegrationA hosted page on book.zoreal.com (book.zoreal.com/<handle> lists the active event types and book.zoreal.com/<handle>/<slug> is one of them), a one-tag snippet (embed.js, inline where the tag stands or as a layer on the host’s own button, rendered in an iframe so the host’s page never runs Book’s code and Book never reads the host’s page), and the SDK family the snippet is built from: @zoreal/book-js and @zoreal/book-react on npm, first released 2026-09-10. Calendars are local or connected Google calendars, for busy time and event writing.The Microsoft Graph Bookings API for shared bookings ("The API is not applicable for personal bookings."), whose walkthrough starts with a Microsoft 365 Business Premium subscription; Exchange Web Services for data export and a .TSV report of the past 120 days; an iFrame embed of the booking page; apps inside Outlook and Teams.

Data handling and certificationsEvery stored instant is UTC, every rule is in its schedule’s zone and every display is in the reader’s zone. On an open event type the guest confirms their address with a six-digit code before the booking is made; the guest is not asked for a phone number. Busy time is read from the host’s connected calendars and a booking is written into the host’s connected calendar. A retention period for bookings is not stated on zoreal.com as of September 2026. Organization-level, as zoreal.com lists them for Bynn Intelligence, Inc.: SOC 2 (attestation), PCI DSS (SAQ A), GDPR (data protection), ISO/IEC 27001:2022 (information security certification) and CSA STAR Level One (cloud security self-assessment). No Book-specific certification is stated on zoreal.com as of September 2026."All Bookings data is stored within the Microsoft 365 platform and in Exchange Online.", in shared mailboxes holding customer, staff, service and appointment details, under the compliance policies that apply to Exchange shared mailboxes; a customer data usage consent checkbox whose acceptance date and time is recorded; search-engine indexing of the page can be disabled; deleting a calendar deletes its Exchange mailbox. No certification specific to Bookings is stated: Bookings follows the data storage policies of every Microsoft 365 app, and Microsoft 365’s platform offerings are listed on Microsoft’s compliance hub (overview; Shared Bookings FAQ).

Where ZOREAL Book and Microsoft Bookings agree

Both are booking pages with appointment types and per-type policies: Bookings sets time increments, lead time and maximum days in advance and takes the staff member’s free/busy from their connected calendar; ZOREAL Book computes slots from the host’s availability schedule, date overrides, public holidays, buffers, minimum notice and booking window, minus busy time from every connected calendar. Both send the guest a confirmation carrying the appointment for their own calendar, an ics attachment on Bookings’ side and a calendar file on ZOREAL’s.

Both refuse two bookings of the same slot at the service, not at the client: "Bookings will only let one person book that time" when several people try at once, and a ZOREAL Book database exclusion constraint refuses a second booking over the same minutes for the same host. Both put the online appointment in a room of their own product, a Teams meeting link on Bookings’ side and a ZOREAL Meet room created on confirmation on ZOREAL’s, and both keep an in-person appointment, with the business address on Bookings and a booking that does not end in a call living on the same calendar as the calls in ZOREAL Book.

Neither claims that the person who booked is the person who turns up. Bookings’ tenant-restricted page shows that the booker signed in with an account of the organisation, and Microsoft states nothing beyond that. ZOREAL Book says so in writing: a confirmed booking asserts that a guest chose this slot and the slot was free on every calendar the host connected at that moment, and who is in a call is what Meet’s own presence check proves, in the call.

ZOREAL Book may fit you if

  • You want the booked call to take place in a ZOREAL Meet room created on confirmation, where the host can require a presence check at the ZOREAL Presence or ZOREAL Identity level.
  • You take payment at booking on your own Stripe account, with a ten-minute hold and a booking that asserts the guest paid before the slot was held.
  • Your busy time lives in Google Calendar, read for busy time and written to with the booking, with blocks written to the account as busy events.
  • You want scheduling that comes with the meeting product’s own plans. Included in the Free Meet plan (unlimited meetings up to 40 minutes, scheduling and calendar invitations); a guest books and joins without an account.
  • You want the guest’s email address confirmed with a six-digit code before an open booking is made.

Microsoft Bookings may fit you if

  • Your organisation already holds a Microsoft 365 or Teams licence on Microsoft’s Bookings list and wants scheduling at no separate price (Shared Bookings FAQ; plan pages).
  • Your staff’s availability lives in Exchange Online and you want bookings kept inside the tenant’s compliance policies (overview).
  • You want a Teams meeting link on every online appointment, joinable by browser, app or phone dial-in (overview).
  • You need shared booking pages with staff assignment, group services with a maximum attendee count, multi-staff services and a Graph API (define your services; Graph API overview).
  • You want SMS reminders, with a Teams Premium licence and United States, Canada or United Kingdom phone numbers (SMS notifications page).
