Hi all, Exchange 2007 SP3 RU2 I am trying to create a rule that will remove the header X-Auto-Response-Suppress when the mail is sent to a specific distribution group. For some reason we cant remote that header, i can remove the Subject header or the X-MS-Has Attach header, but nothing happens when i try to remove X-Auto-Response-Suppress. Here is how the rule looks like: Apply rule to message > Sent to a member of TESTGROUP and sent to users INSIDE the organization and when the TO contains TESTGROUP > remove X-Auto-Response-Suppress Any help would be really great! Thx, Zarko

Yes, based on my test in the lab, the header can’t be changed or removedPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question. This can be beneficial to other community members reading the thread.
