I have an exchange server 2013 that is on the latest cu. Right now when I try setting up external out of office replies they do not get the oof reply. In digging into this I found this in the message tracking log :

The allowedOOFType is set to external but for some reason the reply message is getting dropped. I cannot even search for the reply in the message tracking log on ecp. Would this be because of a rule on my exchange server or would this be an issue due to the configuration on the exchange server?
