Hello Mirela_Buru I have another scenario which is on-premise exchange with high availability (DAG) and available on 4 sites. Each site has virtual Exchange and primary DB on each site is located on same physical location of user mailbox. All users' are on single domain, and each geographical site has a DC replicated and synched with other DCs on another sites without any issue. Also, exchange DAG is healthy. Free/Busy is functioning only within same sites! and Free/Busy does not work across all sites! Example, when a user on site#1 is try to look for Free/Busy information for a user mailbox on site#2 then he/she will get error message "calendar; could not be updated" and on "scheduling assistance error is no information!!". Sites are connected together using MPLS connections.
Any suggestion?
Thank you
