A simpler alternative to an Outlook group calendar
An Outlook group calendar only works well when everyone is inside the same Microsoft 365 organisation. TangoHive is a shared calendar anyone can subscribe to from one link - no Microsoft account, no login, and it lands in the calendar app they already use, including Outlook itself.
Outlook group calendars are built for coworkers inside one company. The moment your group includes people outside it - parents, volunteers, members, a booster club's families - the cracks show: they need a Microsoft account, there is no public link to share, and nobody outside the tenant can reliably subscribe.
TangoHive is built the other way around. The calendar lives at a link. People subscribe once and every change flows to their phone, whether they use Apple Calendar, Google Calendar, or Outlook. You are not asking anyone to join Microsoft 365 to see when the next meeting is.
What this kind of group actually needs
Everyone can see it, not just the org
A group is rarely one company. Anyone should be able to open the calendar from a link, with no account and nothing to install.
It subscribes into the app they already use
People will not check a separate calendar. Events should flow into the Apple, Google, or Outlook calendar already on their phone, and stay updated there.
A public link you can put anywhere
On a newsletter, a website, a printed flyer. One address that works for everyone, not a tenant-internal calendar.
One person can run it without IT
No admin console, no Microsoft 365 licences, no tenant settings. Paste a schedule, share the link, done.

Good to know
- Not a replacement for Outlook or Microsoft 365 inside a company - if your need is coworker free/busy and room booking in one tenant, Outlook is the right tool.
- Not an email or document suite. TangoHive is the shared calendar and the group's communication around it.
Common questions
- Why can't people outside my company see my Outlook group calendar?
- Outlook group calendars live inside a Microsoft 365 tenant. People outside it generally need to be invited to the organisation or given a Microsoft account, and there is no public subscribe link. TangoHive gives every calendar a link anyone can open or subscribe to with no account.
- Can people still use Outlook to see a TangoHive calendar?
- Yes. TangoHive publishes a standard calendar feed, so a TangoHive calendar subscribes cleanly into Outlook, Apple Calendar, and Google Calendar alike.
- Do we have to move off Microsoft 365?
- No. Keep Microsoft 365 for work. TangoHive is for the calendar you need to share with people who are not on your company's tenant.
- What does it cost?
- It is free while we are in early access, with no card required.
