Hi there,
Trying to set the 'RequireSenderAuthenticationEnabled $true' property for a mailbox within a specific OU, from our DC. DC has created a remote PS session to our Exchange server. Currently logged in as domain admin.
I receive the above error when executing the full command. Have noticed that the 'Enable Inheritance' button is showing, when checking security permissions for the Administrator account within AD. I can't think of any, but am I likely to cause any new issues by enabling inheritance? (not sure when the user account was set to not).
Thanks.
