Out of Office messages are not being delivered to any external recipients when our users enable them on their mailboxes. Internal recipients do receive the messages, but no external recipients do.
I don't see an obvious organization-wide setting to enable/disable out of office messages to external recipients...and it was working when we were running Exchange 2010. Is there something specific we need to do to enable it on 2013?
We are running Exchange 2013 on premises with all current SPs and Updates applied.
