How to use Out of Office functionality?

Hi,
I need to use the 'Out Of Office' functionality. This applies to internal messages (not e-mails) in SAP Business One. In 'Messages / Alerts Overview' window, after clicking 'Out of office' button, I selected the 'I am not in the office' option. 'Job Service - Mailer' service is started and appropriate database (in the Service manager) is selected. Alerts work correctly.

After these settings, if other user has sent an internal message to a person who is out of the office - there is no auto reply/alert to user who sent the message.

Does something else have to be set? What is the default auto-response message (internal) and is it possible to edit the content of auto-response message?

Regards
Krzysztof

P.S. Apparently there was a SAP note: '871076 - Out of Office functionality'. However this SAP Note has been removed... Btw. do you know why some of SAP notes are removed? I've seen it several times.
