We have Exchange 2007 with a BES server and clients running Outlook 2003 and Outlook 2007. When an end user turn on their out of the office notice, it works however the email attachment is not the latest that they just put onto the server. It the prior notice they submitted.
To resolve the issue, we are having the end users set the OFO notice on the Outlook client and their BlackBerry's. Then it works correctly.
