Sharing Your Outlook Calendar Availability With Clients and Vendors

Starting a project with a trusted client or vendor? Stop asking for availability and going back and forth constantly. Here's a quick guide on how to start sharing your Outlook calendar with another domain.

1.     Ensure that you have the proper admin permissions to change settings on behalf of your organization. If not, you can forward these instructions to your IT team.

2.       From the Microsoft 365 admin center dashboard, go to Admin > Exchange.

3.       Go to Organization > Sharing on the left hand tool bar.

4.       Under Organization Sharing, click Add organization relationship.

5.       Configure the relationship


a.       In new organization relationship, in the "Relationship name" box, type a friendly name for the organization relationship.

b.       In the "Domains to share with" box, type the domain for the external Microsoft 365, Office 365, or Exchange on-premises organization you want to let see your calendars. Any connected domains will also link once configured.

c.       Select the "Calendar free/busy information sharing" check box to turn on calendar sharing with the domains you listed. Set the sharing level for calendar free/busy information and set which users can share calendar free/busy information.

d.       Review the relationship and click next to configure.


That's it! It really is just that simple. You've saved yourself the pain of the dreaded back and forth "availability dance".
