My client is in the process of being divested from a parent company, and users have already been migrated to a new AD forest and Exchange org. On the parent company, they want autoreplies for the divested users (easy enough), but they want them to always fire for every received message.
In Exchange 2010 and the OWA GUI, it states that the OOO/autoreply will be sent once for each sender. This is not configurable, AFAICT. Management wants the configured autoreply to fire every time. Is this something that I can force?
Alternatively, I considered creating a simple inbox rule to fire on every message that is received after "x" date (today), with the action to have the server reply with an appropriate message. However, this rule is only visible/configurable in Outlook, not OWA.
Thus I can't have my users (already migrated, thus Outlook is using the new domain) set this in Outlook in the old domain - not without walking them through trying to make new profiles manually connected to the old Exchange org. No thanks.
Also, the New-InboxRule cmdlet does not appear to be able to configure the "reply" action, unless I'm missing something, so I can't do this in a PowerShell script.
Any ideas on other ways to solve this problem? A custom bounce Transport rule looks likely to be ignored by senders - since the custom message is buried in the 5.7.1 error code, and it does not resemble normal OOO messages.
/ Bah humbug. Just found this one. Unless things have changed, I'm likely out of luck. Exchange out of office, sending an OoO reply for every email
