Calendox vs Calensync: Multi-Way Sync, Bookings and Price

Questions

How is Calendox different from Calensync?

Calendox keeps two or more calendars in step with one multi-way sync. Its Personal and Business plans add a unified calendar and booking pages with Google Meet, Microsoft Teams or Zoom links. Calensync copies events with one rule per source and destination, and its one plan lists Apple Calendar and ICS feeds, unlimited linked accounts and sync mappings, and scheduling links. Calendox syncs one-way or multi-way between Google, Microsoft and on-premises Exchange Server calendars. On Enterprise it syncs calendars between Microsoft 365 tenants.

How many syncs does it take to keep three calendars in step?

One in Calendox. A multi-way sync holds two or more calendars, each from a different connected account. Every calendar in it is both source and target: add, change or delete an event in any of them and the change reaches the rest. Multi-way sync is on every plan and in the trial, and the whole sync takes one sync slot.

On Calensync, each rule copies one source calendar into one destination: its Google example creates one rule from the work calendar into the personal one and another back, from the personal calendar into the work one. Its Apple Calendar announcement describes creating a rule in the direction you need. Keeping three calendars in step in every direction takes a rule for each direction you want covered, and Calensync lists unlimited sync mappings.

Is Calendox cheaper than Calensync?

No. Calensync's one plan costs less per person than Calendox Basic, Standard and Premium, billed monthly or annually, and it lists unlimited linked accounts and sync mappings. The pricing table above prices each scenario per person, using Calensync's US price; its pricing widget shows a local price by country.

The plans include different things. Calendox Basic, Standard and Premium allow 2, 5 or 25 connected calendars and the same number of syncs. Each includes multi-way sync and the unified calendar. Booking pages are included too: 2 on Basic, unlimited on Standard and Premium with fair-use limits. A Business team pays the same per seat, and plans and billing lists every plan's limits. Current prices are on the pricing page, in US dollars, and taxes may apply.

Calendox Enterprise is priced per imported secondary-tenant calendar, not per user, and covers admin-run sync between Microsoft 365 tenants, so the table doesn't set it against Calensync's per-person plan.

Which calendars connect to Calendox and to Calensync?

Calendox connects three providers. Google Calendar works with Gmail and Google Workspace accounts, and Microsoft Outlook with Outlook.com, Hotmail, Live.com and Microsoft 365 work or school accounts. On-premises Exchange Server 2016 or later connects the calendars in your own mailbox, with your mailbox address and Exchange password. Apple iCloud, CalDAV and ICS feeds are not supported. Calendars you can only view can't be imported, and Microsoft calendars owned by another mailbox can't be synced from your account.

Calensync's home page lists Google, Outlook, Apple and iCalendar (.ics) calendars, with ICS feeds as read-only sources. Apple Calendar connects with an app-specific password, and Calensync's May 2026 announcement describes Apple Calendar as a source and a destination.

Which Calendox features go beyond calendar sync?

A unified calendar you work in and booking pages, both on every Personal and Business plan. Calensync's FAQ says you can merge calendars from different providers for a unified view. That means copying their events into one of your existing calendars with sync rules. Calendox also gives you a calendar of its own.

• Unified calendar. Your connected Google, Microsoft and Exchange Server calendars appear together in one working calendar in the web app, color-coded, with six views from Agenda to Year. Create or edit an event there and Calendox writes it to the calendar it belongs to. A calendar view is not listed on Calensync's website.
• Booking pages. A booking page offers only the slots that are free across every connected calendar, unless you limit it to chosen calendars. Each booking can carry a Google Meet, Microsoft Teams or Zoom link. Meet works on a Google destination calendar, Teams on a work or school Microsoft one, and Zoom on any destination, Exchange Server included, once Zoom is connected. Basic has 2 pages; Standard and Premium have unlimited pages, with fair-use limits. Calensync's plan lists meeting scheduling links, each with working hours and a source calendar behind it. Zoom and Microsoft Teams links are not listed on Calensync's website. Its app offers an optional Google Meet link (Calensync's dashboard app code).

Enterprise accounts have the tenant sync only, with neither feature.

How does Calendox sync calendars between Microsoft 365 tenants?

With an Enterprise account, which an administrator runs for whole organizations rather than each employee for their own calendars. The administrator of each Microsoft 365 tenant consents once, so employees never sign in, and the Calendox admin then imports and pairs calendars from a tenant dashboard. On Calensync's teams page, each person configures their own calendar sync, and administrators manage the team's subscriptions from one dashboard. An admin-run sync between Microsoft 365 tenants is not listed on Calensync's website.

The first tenant you connect is the master tenant, and its calendars are free; every secondary-tenant calendar you import takes a seat. Pairs form on their own when the email username and the calendar name both match, and you add the rest by hand or from a CSV file. A sync needs at least two connected tenants, and only Microsoft 365 tenants can be connected. What Microsoft 365 shares between tenants without a sync tool is covered in our guide to tenant-to-tenant calendar sharing and sync.

How do the trials compare?

Calendox gives you 14 days and Calensync 7, and neither asks for a credit card. On a Personal or Business account the Calendox trial runs at Premium-level limits, which means 25 calendars, 25 syncs, unlimited booking pages with fair-use limits, multi-way sync and the unified calendar. An Enterprise trial can sync up to 5 imported secondary-tenant calendars, counted across all secondary tenants. Your syncs pause if the trial ends without a subscription, and your connections and settings stay until you subscribe. Members of a Business team each use their own trial until the team subscribes.

Calensync's home page offers a 7-day free trial with no credit-card commitment.

Calendox is also sold through Microsoft Marketplace, where plans include a free trial run by Microsoft on terms shown at checkout.
