Exchange 2k7 - Out of office

[Edu-IT]

I know for sure that Exchange 2k7 is not sending out of office auto replies, for anyone, yet what I'm not sure about is why.

I briefly tried to look into this before but it got put on the back burner. Are there any logs on the Exchange server which could help me to identify why they're not being sent?

Is it enabled in Exchange?

Have a look at these:

You Had Me At EHLO... : Exchange Server 2007 Out of Office (OOF)
Exchange 2007 Out of Office - Exchange 2007 IW Connections - Site Home - TechNet Blogs

It's set at:

· External(the default): This setting allows only Exchange 2007 external OOF messages to be sent to the target domain but blocks internal OOF messages or OOF messages set using Exchange 2003. If you currently block OOF messages to other domains, you probably want to use this setting in order to keep the same behavior for Outlook 2003 users but allow Exchange 2007 external OOF messages out for those who specifically choose them.

Accounts can send externally too, I checked using EMS.
