Question

_{Thursday, October 25, 2018 3:54 PM}

We are merging with an organisation who have already federated their on prem exchange 2010. I have checked by running

Get-federationinformation -domain

<u5:p>We want to share free/busy information with them, and their endpoints all have Outlook 365.</u5:p>

<u5:p>If I federate my Exchnage 2016 (i found this link below) </u5:p>

https://support.microsoft.com/en-us/help/10092/troubleshooting-free-busy-issues-in-exchange-hybrid-environment

It Look like i can achieve this.

However my Question is.... Do all of our endpoint need Outlook 365 to view the free busy information, or will it still work with a mix of 2010, and 2016 (not 365)

Thanks

Hi Dwight Bottomley,

That article is used for Exchange hybrid environment, isn't suitable for a federation environment.

About federation free/busy sharing, you can have a look about those two articles：

1. How does Federated Calendar sharing work in Exchange 2010?

2. Configuring federated sharing between Exchange organizations (Exchange 2016 works like Exchange 2013, so Configure free/busy sharing between Exchange 2013 and Exchange 2010 SP2 organizations is also suitable for you)

Step 1: Create and configure a federation trust

Step 2: Create an organization relationship

Step 3: Create a sharing policy

Step 4: Configure an Autodiscover public DNS record
