We have a hybrid Exchange 2013\Online setup. I'm trying to setup Free\Busy Sharing between my Exchange Org (Production) and another tenant (test) in Exchange Online. I am able to see the Free\Busy for my non hybrid (test) tenant but have issues with the hybrid(production) environment sharing out it's details. I'm pretty sure this has something to do with the Federation Information in the hybrid.
If I use the below command I can see all the domains, but my tenant domain name is missing.
Exchange 2013:
Get-FederationInformation -domainnamemydomain.com | Select-Object -ExpandProperty DomainNames
If I run the below command I get my tenants federation information that doesn't contain my domains.
Exchange Online:
Get-FederationInformation -domainnametenant.onmicrosoft.com | Select-Object -ExpandProperty DomainNames
If I add the Exchange 2013 federation details into my test tenant I can see the calendars hosted in 2013. If I use the tenant federation information I can see the online details.
How do I get both to work?
