Assigning a remote mailbox to an on-premises user

Hi everyone,

I need to assign a remote mailbox to an on-premises user but I can't find the edsvaMsExchEnableRemoteMailRoutingAddress property.

I checked the user properties under the "Object > Advanced Properties" tab..

I activated the "Show all possible attributes" and "Include attributes with empty values" view but it doesn't appear

My Active Roles is 8.0.1 version

Thanks in advance to everyone
