Exchange Online Free/Busy federation between two Office 365 tenants
I have recently tried to establish the GAL Federation between two of my Office 365 Exchange Online tenants to share the Free busy Availability between those domains. I have used the domains exchangeonline.in and the free one manuphilip.onmicrosoft.com
1) Connect to Exchange Online through PowerShell as an administrator user on one of the domain (https://technet.microsoft.com/en-us/library/jj984289(v=exchg.150).aspx)
2) Find the existing Federation info between the domains under consideration. Substitute the domain name when asked as below:
Get-FederationInformation -DomainName
3) Create a New Organization Relationship between the domains and set the Free Busy Properties. In this step, I am going to set the FreeBusyAccessLevel as ‘AvailabilityOnly’
Get-FederationInformation -DomainName “Domain Name” | New-OrganizationRelationship -Name ‘Federaion’ -Enabled $true -FreeBusyAccessEnabled $true -FreeBusyAccessLevel ‘AvailabilityOnly’ -FreeBusyAccessScope $null
4) Now check the Scheduling Assistant in owa or outlook and see it has shared as below: I have tried to check the availability info of a mailbox located in the federated domain
5) Similarly, you may also set the ‘FreeBusyAccessLlevel’ as ‘LimitedDetails’ for the existing OrganizationRelationship as below:
Set-OrganizationRelationship ‘Test-Federation’ -FreeBusyAccessLevel LimitedDetails
Hi, is there a possibility to do the same between O365 tenant (hybrid coexistence mode) and Exchange 2010 from another forest? Thank you
I guess YES, provided federation should be enabled. I need to check how it is going to work anyways
Hi,
Is this solution share the adress book between the 2 tenants ?
Thanks for your answer.
Hello,
What if if want more – share global address book, skype for bussiness users, sharepoint access in both tenants?
We need to be able to share Conferensrooms between 2 tennants. With Contact object for rooms in the other tennant the ad a room feature in Outlook is inconsistent, any suggestions on how to solve this?
Have you established Federation between the two tenants? Microsoft explains that here: https://technet.microsoft.com/en-us/library/jj676768(v=exchg.150).aspx
Why did not we use sharing policies to share the Free/Busy information between two different tenants?
Sharing policy would enable the F/B information to be shared.
Appreciate this post. Will try it out.
