Microsoft Bookings vs Calendly (2026): which should you use?

Choose Calendly if you need round-robin assignment or routing forms, want to take payment at booking, or want GA4, Meta Pixel and webhooks without building anything yourself, and you are comfortable paying per host seat. Keep Microsoft Bookings if your team already works in Microsoft 365, your appointments are straightforward services with Teams links, and you would rather not add another vendor that holds customer data and calendar access.

Both products put meetings on Outlook calendars and can generate Teams links. The difference is everything around the booking. Calendly is a standalone scheduling product with free and paid tiers. Bookings is part of Microsoft 365 and stores its data in Exchange Online, which is either a strength or a limit depending on what you need.

Side-by-side comparison#

Prices are in USD as listed on Calendly's pricing page in September 2026. Vendors change prices often, so confirm before you buy.

Scheduling and routing#

Bookings gives you two kinds of page: shared booking pages, which have services and staff, and personal "Bookings with me" pages for one person's own time. On a shared page, a customer can pick a staff member or choose "Anyone". Microsoft's FAQ says staff are then "assigned randomly", and that "there's no way to ensure equal distribution… or to cap the number of assigned appointments to each staff member". Community reports describe alphabetical-first assignment instead, so the two sources disagree. There is also no per-staff time zone setting, and appointments can only be edited in the Bookings web portal, not from Outlook. The details are in does Bookings support round robin.

Calendly puts round robin on its Teams and Enterprise plans, and routing forms ("Create forms, screen invitees, and route leads") on Teams and above. The Free plan is limited to one event type and one calendar connection. Paid plans connect up to six calendars. Outlook connects through a Microsoft sign-in on every plan, and you can pick up to four sub-calendars for conflict checks. Teams meeting links are on all plans, but Calendly says you need "a Microsoft 365 Business or Office 365 Education account".

Reminders differ too. Bookings sends email reminders anywhere from 15 minutes to two weeks before an appointment. Its SMS option is part of Teams Premium and needs a US, Canada or UK number, although an older passage in the FAQ says SMS is "available in North America" through Skype or Twilio. Calendly's Automations, on Standard and above, cover reminders, follow-ups and text messages, with up to 50 automations per user or team.

Embedding and branding#

Microsoft documents one embed method: an iframe whose code sits on the Booking page tab of a shared booking page. You can set colours and a logo. No custom CSS or custom domain is documented. Two access settings matter for embeds: "Require a Microsoft 365 account from my organization to book" and "Disable direct search engine indexing". Personal pages have no embed code at all. See where to find the Bookings embed code for the click path.

Calendly offers three embed types on all plans: inline, pop-up text and a pop-up widget. They load through widget.js, and Calendly notes the scheduler "loads in an iframe by default". Custom embed colours (background, text, primary) are for paid plans, and removing Calendly branding starts at Standard. Calendly doesn't publish an official React package. The popular react-calendly package is community-maintained.

Tracking and analytics#

This is where the two differ most. Bookings' only built-in attribution is a RefID parameter on the booking page URL, which shows up in a downloadable TSV report. Microsoft gives two windows for that report: "last four months" in one article and "past 120 days" in the FAQ. No GA4, Google Ads or Meta Pixel integration is documented, and Microsoft staff have confirmed there is no native redirect to a thank-you page after booking. Because the page is hosted by Microsoft, your tags can't run on it. The practical options are in tracking Bookings conversions in GA4.

Calendly connects GA4 on Standard and above, with "one GA4 Measurement ID per Calendly organization". Its events include invitee_select_day and invitee_meeting_scheduled. Calendly says it "doesn't support direct integration with Google Tag Manager", and Google Ads conversions come in through GA4's conversion import. The Meta Pixel integration is also on Standard and above and is "built and managed by Meta". If you use the JavaScript embed, the parent page receives postMessage events such as calendly.event_scheduled, which a developer can push to the dataLayer. A plain iframe gets neither the events nor auto-resize.

Integrations and webhooks#

Microsoft doesn't offer Bookings webhooks. The Microsoft Graph Bookings API covers shared bookings only, not personal pages, and application permissions need tenant admin consent. The Power Automate connector is still in preview. It has three triggers (created, cancelled, updated), only Bookings admins can build flows with it, and each Bookings mailbox is limited to five flows. Does Bookings support webhooks covers the workarounds.

Calendly lists webhooks on Standard, Standard Plus, Teams, Teams Plus and Enterprise. Its API accepts GET and POST requests "on any subscription plan, including the Free plan", apart from a few Enterprise endpoints. The Scheduling API lets you book meetings from your own apps, but rescheduling through the API isn't supported. The Microsoft Dynamics 365 and Power Automate integrations are Enterprise only.

Payments#

Microsoft's FAQ is direct: "No, there's no payment support in Bookings." Calendly collects payments at booking through Stripe and PayPal on Standard and above. If paid consultations are central to your business, Bookings needs an outside payment step. See can Bookings take payments.

Data and compliance#

Microsoft says all Bookings data is stored in Microsoft 365 and Exchange Online. Each booking calendar is a shared mailbox, and "compliance policies for shared mailboxes in Exchange also apply". Each calendar also creates an unlicensed user entry in Microsoft Entra ID. Bookings is cloud-only and not supported in federated or hybrid setups. The consent checkbox can be made required, and the time the customer consents is recorded.

Calendly's security page lists "SOC 2 (Type 2), SOC 3, CSA STAR, PCI COMPLIANT, ISO/IEC 27001" and says it is "hosted on a leading cloud infrastructure provider". Data residency or region choice is not stated on that page. HIPAA is not claimed on Calendly's pricing or security pages. SSO/SAML is an add-on on Teams and included in Enterprise.

Pricing#

Bookings has no separate price. It is included in Office 365 A3, A5, E1, E3, E5, F1, F3, G1, G3 and G5, and in Microsoft 365 A3, A5, E1, E3, E5, F1, F3, Business Basic, Business Standard, Business Premium, Teams Essentials and Teams Premium. Microsoft announced list price changes for Microsoft 365 that took effect on July 1, 2026, so check current plan prices on Microsoft's site.

Calendly, as listed on Calendly's pricing page in September 2026 (per seat per month, USD):

Only hosts need a seat: "meeting invitees do not require a seat".

When to keep Microsoft Bookings#

• Your organisation already has an eligible Microsoft 365 plan and wants no new vendor or data processor.
• Appointments are simple services (consultations, support calls, advising) where random or chosen staff assignment is acceptable.
• You want booking data to stay in Exchange Online under your existing Microsoft 365 compliance policies.
• Teams links, Outlook calendars and Microsoft's confirmation emails already cover what customers need.

When to switch#

• You need fair round-robin distribution or routing forms that send different leads to different people.
• You take payment at the time of booking.
• Marketing needs GA4 or Meta Pixel conversions without custom development.
• You need webhooks on every booking, without the five-flow Power Automate limit.
• You want to remove vendor branding and control embed colours.

Keeping Bookings and filling the gaps with BookingsXP#

If the only reasons to switch are website and tracking gaps, BookingsXP adds a branded booking widget to your site from your public Bookings link, with no Microsoft sign-in or admin consent. Bookings are still created in Microsoft Bookings, so Microsoft's confirmation email and the Teams link work as they do today. The widget sends funnel events to GA4, Google Tag Manager, Google Ads, Meta and LinkedIn, and writes UTM parameters and click IDs into the booking itself (analytics). It doesn't add round robin, routing or payments, so if you need those, Calendly is the better fit.
