Microsoft Outlook integration

Microsoft calendar scheduling for Outlook & Microsoft 365

Connect your work or personal Microsoft account and share one booking link. Freeslot respects every Outlook status - busy, tentative, out of office - and books meetings straight into your calendar.

  • Work, school & personal accounts
  • Included on every plan
  • Disconnect anytime

Setup

Connect Outlook in four steps

Same flow for Microsoft 365 and Outlook.com - with one extra step if your company controls which apps can connect.

  1. Sign in with Microsoft

    Use a Microsoft 365 work or school account, or a personal Outlook.com, Hotmail, or Live account.

  2. Approve calendar access

    Freeslot asks to read and write your calendars. If your organization requires admin approval, IT approves it once for everyone.

  3. Pick a booking calendar

    Choose which calendar in your mailbox bookings go to - your main Calendar or a separate one - per booking page.

  4. Share your link

    Set your hours and publish. Guests only see times your Outlook calendar shows as free.

Busy-time checks

Every Outlook status, respected

Freeslot reads your Outlook free/busy schedule and your booking calendar live, every time a guest opens your page - and again when they confirm.

  • Busy, Tentative, Out of office, and Working elsewhere all block the slot
  • Only events shown as Free leave the time open
  • Cancelled meetings are ignored automatically
  • Your main calendar still counts when bookings go to a separate calendar
  • Add a Google or Zoho calendar and check them all together Professional

Booking sync

Bookings land in Outlook as real meetings

Freeslot creates the meeting in the Outlook calendar you chose, with your guest as a required attendee - so the invite comes from your own mailbox.

  • Subject is your page name and the guest's name
  • Guest contact details, notes, and chosen services in the body
  • Outlook reminder 10 minutes before
  • One-on-one meetings show as Busy; group sessions show as Free so open seats stay bookable
  • Cancel in Freeslot and the meeting is removed from Outlook
  • Delete it in Outlook and, on its next check, Freeslot cancels the booking and emails your guest

Who it's for

Made for Microsoft-first workplaces

If your day runs on Outlook, outside meetings should land there too - with the statuses your colleagues already rely on.

Corporate teams on Microsoft 365

Take external meetings in the calendar IT already manages, with no extra calendar account just for bookings.

Consultants & agencies

Clients receive a proper Outlook meeting request from your own address, alongside Freeslot's confirmation.

Recruiters & HR

Candidates book screening calls into Outlook, and tentative holds for hiring panels stay protected. Route across interviewers with team scheduling.

Legal, finance & advisory

Out-of-office and tentative time is respected, so clients only book when someone is genuinely available.

Universities & schools

Advisors and faculty share office-hours links against the school Microsoft 365 calendar they already use.

Solo pros on Outlook.com

Personal Outlook.com and Hotmail calendars work too - no Microsoft 365 subscription needed.

FAQ

Outlook scheduling questions

Does Freeslot work with personal Outlook.com accounts and Microsoft 365?

Yes, both. Connect a Microsoft 365 work or school account, or a personal Outlook.com, Hotmail, or Live account.

My company says admin approval is required. What do I do?

Some Microsoft 365 organizations only allow apps an administrator has approved. Ask your IT admin to grant consent for Freeslot in Microsoft Entra ID. After that, everyone in your organization can connect without the prompt.

Which Outlook statuses block my availability?

Busy, Tentative, Out of office, and Working elsewhere all block the time. Only events shown as Free leave it bookable, and cancelled meetings are ignored.

Does Freeslot create Microsoft Teams meeting links?

Not automatically yet. Add your Teams meeting link as the meeting location on your booking page, and guests see it on the page and in their confirmation email.

Can bookings go to a calendar other than my main Outlook calendar?

Yes. After connecting, pick any calendar in your mailbox for each booking page. Freeslot still reads your main free/busy schedule, so meetings on your main calendar block time too.

Can Freeslot check my Google or Zoho calendar alongside Outlook?

Yes. On Professional, Freeslot checks up to six connected calendars - Outlook, Google, and Zoho in any mix - before offering a time, so a personal Google calendar can block your work hours in Outlook.

What happens if I delete the meeting in Outlook?

Freeslot treats the booking as cancelled. The next time it checks your calendar, the booking is marked cancelled, the time opens up again, and your guest gets a cancellation email.
