I'm trying add a user as a resource delegate on a resource calendar. First, I get the current list of resource delegates using the following command: Get-MailboxCalendarSettings confRoom | fl Then I copy the list of delegates and append the user. The command looks like this: Set-MailboxCalendarSettings -Identity "company.local/ou/ou/ou/confRoom" -ResourceDelegates "company.local/ou/ou/ou/user1", "company.local/ou/ou/ou/user2", "company.local/ou/ou/ou/user3", "company.local/ou/ou/ou/user4", "company.local/ou/ou/ou/user5", "company.local/ou/ou/ou/newUser" I get the following error: WARNING: An unexpected error has occurred and debug information is being generated: Default Scope and Search Root cannot be set at the same time. Set-MailboxCalendarSettings : Default Scope and Search Root cannot be set at the same time. If I take the new user off the end, the command works. I verified that all the users are in the same OU. What gives? Thanks
