I have a co-worker who was on vacation recently. He set the OOF to display messages to internal and external people. Now he's back, switched off the OOF in OWA.
According to OWA all OOF messages are disabled.
External people don't get the OOF message anymore, but internal people still get the message.
Is there a way to disable/switch off the OOF in the powershell or do something else to disable it?
