Free/Busy Federation Between Office365 Tennent & Hybrid Office365/On-Premise Tennent

We're trying to setup free/busy time calendar sharing between our company, and another we are partnering with.

We are running a hybrid environment, with an on-premise Exchange 2010 server, and Office 365 cloud, where all our mailboxes have just been migrated too.

The other company is running fulling Office 365, with no remaining on-premise servers.

We have both setup the Microsoft Federation Gateway and then run the following PowerShript:
Get-FederationInformation -DomainName thepartner.com | New-OrganizationRelationship -Name "The Partner" -FreeBusyAccessEnabled $true -FreeBusyAccessLevel AvailabilityOnly

However, although we can see their free/busy time (although only via OWA and Outlook 2010 SP1 - Outlook 2007 SP3 doesn't work). The partner company can't see any of our free/busy time, with OWA or Outlook.

Could anyone offer any suggestions on how to fix, or where to start troubleshooting?

Run the following on your exchange server:
get-federationtrust | set-federationtrust -refreshmetadata

If you set up ADFS earlier than January, they have the wrong SSL information to properly pass free-busy data.

Thanks for the reply. I've run the PS command, and it completed successfully. I'm now waiting for feedback from the partner company to see if this has resolved the issue. I will report back as soon as I hear anything!

I've received a reply from the partner federated company, and the issue remains, they are unable to see our free/busy time in Outlook 2010 or OWA.

I have attached the below pic as an example of what the federated company can see via OWA.

Granular recovery for Microsoft Exchange

With Veeam Explorer for Microsoft Exchange you can choose the Exchange Servers and restore points you’re interested in, and Veeam Explorer will present the contents of those mailbox stores for browsing, searching and exporting.

Follow this: http://howexchangeworks.com/2009/07/diagnostic-logging-in-exchange-2010.html

And enable high or expert logging for all options under the availability service, then have your partner attempt to access a calendar for one of your on-prem users. Once they do, turn the logging back down and check the Application log for errors relating to the Availability service. That will give you more information about where the failure is occurring.

Hi,

I had to open a ticket with Microsoft Premier support who were able to resolve this after looking at the commands we both ran initially, and how the Federation Gateway was configured for each company.

Turns out the partner company were federating with our on premise instance, not the Office 365 cloud mailboxes. Microsoft gave us the below command, which the partner company had to run, so they could change the federation over to the cloud:

Set-OrganizationRelationship "Our Company" -TargetApplicationUri outlook.com -TargetAutodiscoverEpr https://pod51042.outlook.com/autodiscover/autodiscover.svc/WSSecurity -DomainsNames ourdomain.com,ourdomain.onmicrosoft.com,ourdomain.mail.onmicrosoft.com

Open in new window

As soon as the partner company ran this, they were suddenly able to see our free/busy time.
