Sign in with Microsoft
Anyone can continue with Microsoft. Work, school and personal accounts can sign in, and Freesbe links Microsoft to the account with the same confirmed email.
Freesbe works with Microsoft 365 in two ways. People sign in with their Microsoft account, and on Corporate admins can require Microsoft sign-in for everyone. People also connect their Microsoft calendar, so teammates see busy times when scheduling and their status shows In a meeting during Outlook events.
For Companies on Microsoft 365 who want one account for chat, calendar and sign-in.

Start free with up to 10 people and try it today, or book a 20-minute demo with the people who make Freesbe.
Meeting invites carry a calendar file Outlook accepts, with a reminder about 10 minutes before the start. Edits and cancellations update everyone's calendar.
