When client sets Out of Office (int and Ext) via Outlook 2007 or OWA it causes "554 5.7.1 <>: Sender address rejected: Access denied" in the MS Exchange Troubleshooting assistance. There is no NDR and no reply. Found this on multiple of our clients servers.
Looking in Microsft Exchange/Organization Configuration/Hub Transport/ Remote Domain there is "Default" and "Windows SBS Companyweb domain". On the laters properties is an "Out of Office messages types delivered to this remote domain", tried ticking all options (when select none nothing is attempted to send) otherwise I see the same issues.
The server sends/receives otherwise OK.
All help is appreciated.
