I have a problem which started out of the blue a few months back, probably after a rollup update install (but I can't be sure).
Basically, when a user sets their Out of Office autoreply in Outlook (and they set one for external users, and one for internal), if anyone emails them the sender gets both auto replies. This happens regardless of whether they are internal or external to the firm.
It is also worth mentioning we run both Exclaimer's Exchange footer disclaimer software, and Jam Software's Exchange Server Toolbox on our one Exchange server. Both firms say this problem shouldn't be caused by their software (and I have tried removing it to no avail, as a test).
Any thoughts greatfully received - perhaps I can use the Exchange Shell to reconfigure something network wide that may have got messed up during the Rollup update?
