Hello! We have been migrating our networks to a one domain, and we are currently having two domains with trust. Migrated users are using linked mailbox, and now we are having problems to get room mailbox calendar data to the migrated users. When opening calendar, busy information is only shown, but no details. Information was available to users before linked mailbox, so is this permissionproblem? Is it possible to deliver the information to linked mailboxes at all ? I tried to set the permissions via powershell without proper results. Exchange server is 2010, Platform 2008 R2.

Hello, What is PowerShell command you used to set permissions? Did other user mailboxes work well? If you follow this command to set permission on room mailbox calendar, can linked mailboxes see the information on calendar? Set-mailboxfolderpermission -identity Roommailbox:\Calendar -User anonymous -AccessRights reviewer Thanks, EvanEvan Liu TechNet Community Support
