In the Active Directory Users and Computers Microsoft Management Console (MMC), follow these steps:
- On the View menu, make sure that the Advanced Features option is selected.
- Double-click the distribution group that automatic replies do not work for.
- On the Exchange Advanced tab, click to select the Send out-of-office messages to originator check box.
- Click OK to close the properties of this group.
After this change replicates to all of the domain controllers that Exchange 2003 or Exchange 2000 is using, the automatic replies feature works as expected.
