Sharing calendar between two domains in the same tenant

Question

I have two domains in the same tenant.

I want to configure settings in such a way that ,

anyone on @domain1.com can see the availability of anyone on @domain2.com’s calendar.

Could someone please provide a documentation on how to implement the same

Answer 1

This is enabled by default, anyone within the same organization can see everyone else's availability info. The domain doesn't matter, as long as they are in the same tenant.

The only thing you might want to adjust is the level of detail exposed, i.e. if you want not just the availability info exposed, but also details about the meeting subject and location. You can do this by adjusting the permission level on the Default principal via the Set-MailboxFolderPermission cmdlet: https://learn.microsoft.com/en-us/powershell/module/exchange/set-mailboxfolderpermission?view=exchange-ps
