Hi all, i need to create an auto-reply for groups in exchange 2007 and i know that we have 2 way: put a noreply.user in the group with out of office activated use server transport rules Well, i can't use the first one because my customer doesn't wat see "out of office" prefix in the subject email and apparently there is no way to modify or delete that prefix-subject but with server transport rules i'm really near to do that applying this rule to messages: when any of the recipients in the To or CC fields are people (where people is my distribution group) send bounce message to sender with enhanced status code If i send an email to this group ONLY it works (except that exchange expands the group and replies an email with 5.7.1 error for each membership, why??) If i send an email to this group AND (to OR cc (internal groups OR internal users) or (external emails)) the whole email is blocked, noone receive this email and the sender receive 1 email for each group, user and external email that i added to email (containing 5.7.1 error message from each membership like usual)... that's weird! example: i send an email to: internal_group1(interal_user1,internal_user2), internal_group2(interal_user3,internal_user4), external_user1 exchange log: RECEIVE - STOREDRIVER EXPAND - ROUTING internal_group1 (obtained 2 emails) EXPAND - ROUTING internal_group2 (obtained 2 emails) FAIL - AGENT (external_user1) FAIL - AGENT (internal_user1) FAIL - AGENT (internal_user2) FAIL - AGENT (internal_user3) FAIL - AGENT (internal_user4) TRANSFER - ROUTING TRANSFER - ROUTING FAIL - ROUTING (internal_user1, internal_user2) FAIL - ROUTING (internal_user3, internal_user4) SUBMIT - STOREDRIVER result: i receive 3 emails with 5.7.1 errors and no-one received the email Any idea to fix it? how i can force exchange to don't expand the groups and just reply with the name of distribution group? Or do you have another good solution to use auto-reply with distribution groups? ThanksDavide Menicucci System Administrator at I.S.I.S. SpA (www.isis.sm)
