Share calendars with external users

Created by Neha Mishra, Modified on Mon, 21 Oct, 2019 at 5:03 PM by Old Tickets Krishna

It’s often necessary to schedule meetings with people outside your organization. To simplify the process of finding mutually agreeable meeting times, Office 365 enables you to make calendars available to “external users,” those who need to see free/busy time but don’t have user accounts for your Office 365 environment.


Note: If you want to share calendars with an organization that uses Exchange Server 2013 (an on-premises solution), the Exchange administrator will need to set up an authentication relationship with the cloud. This is known as “federation” and must meet minimum software requirements.


Enable calendar sharing using the Office 365 admin center

  • Sign in to Office 365 with your work or school account.
  • Select the app launcher icon and choose Admin.
  • Navigate to Settings > Services & add-ins.



  • On the Services & add-ins page, click Calendar.




On the Calendar page that opens, do one of the following:

  • For Let your users share their calendars with external users who have Office 365 or Exchange, move the slider to On to enable calendar sharing.
  • For Let your users share their calendars with external users who have Office 365 or Exchange, move the slider to Off to disable calendar sharing.
  • If you want to allow anonymous users (users without logon credentials) to access calendars via an email invitation, for Allow anonymous users to access calendars with an email invitation, move the slider to On.
