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?
