Hi Exchange Team,

We have two enviroment for cross forest with a Exchange 2019 in forest A, a Exchange 2019 in forest B and FIM for GalSync. GalSync has been configured to allow cross forest delegation.

Users from both forests are able to open a calendar from the other forest, but the see only "Busy", even if I set owner rights for a user in forest A to a calendar in forest B. Only the "Default" Kalender Permission Settings are taken if User from Forest A views a Calender of User from Forest B.

The Contacts have all the required Attributes like:
mAPIRecipient = TRUE
msExchMasterAccountSID = objectSID from Mailbox
msExchOriginatingForest = Target Forest FQDN
msExchRecipientDisplayType = –1073741818
msExchRecipientTypeDetails = 32768
proxyAddresses = X500: + LegacyExchangeDN from Mailbox; existing addresses

And the Configuration in both forests are based on this article:
https://learn.microsoft.com/en-us/exchange/architecture/client-access/availability-service-for-cross-forest-topologies?view=exchserver-2019

Is the Cross-Forest Availability with cross-forest delegation on Exchange 2019 still supportet?

Thanks for clarification.

    Hi @Joyce Shen - MSFT ,

    Thanks for the link.

    In this case, is the cross-forest delegation with Exchange 2019 still supported by Microsoft?
