Exchange Hybrid Calendar Sharing Not Working

Copper Contributor

Hello All,

 

Kindly suggest me what I should do to solve calendar sharing issue for hybrid environment. My goal is to share calendar information with Limited Details. Our issue is that all O365 users can see the On-Premises users' calendar information, but the On-Premises users can't see the O365 users calendar information not even the free/busy. Our Default Sharing Policy is "Limited Details" for both Exchange Online and Exchange On-Premises.

 

  • We have same Sharing Policy between Exchange On-Premises and Exchange Online. 
  • We have already configured our on-premises domain for hybrid environment with Exchange Hybrid Configuration Wizard.
  • We have already enabled ACL for our environment

 

 

Set-OrganizationConfig -ACLableSyncedObjectEnabled $True 

 

 

  • We have already enabled ACL on the user's mailbox.

WARNING: The federated domain 'onpremises.domaiin' of the user is in the local organizational relationship which normally only contains the domains of external organizations.<p>Thank you very much all of you for your positive supports in advance. I really appriciate it!</p>
