I'm having some issues figuring out what needs to be done or where the issue is.
in the EMC:
Set-Mailbox -Identity userid -RequireSenderAuthenticationEnabled $true returns an error stating "the operation couldn't be peformed because object 'userid' couldn't be found on 'domain controller'.
and...
Set-Mailbox -Identity userid -RequireSenderAuthenticationEnabled $true -DomainController mydomain.controller.dc returns a similiar error except that no matter which of the 2 domain controllers FQDN I state...the object still can't be found.
however...
Get-User userid does return a valid response
in the above 2 instances I've also tried Set-MailUser....but the same results come back.
I've searched for answers and none of the solutions i'm finding lead me to where the issue is.
Any help would be appreciated.
Thanks
