Hi, I am working on an issue, which is: A user is getting emails from a DL, in which he is not a member. The user were previously a member of the group and for some months he is not a member of that group. I have checked everything. Gone through all Nested groups, Checked for any forwarding rules to the user from the DL members and I can't find anything. Kindly help me to trace out the issue.Regards from www.windowsadmin.info | www.blog.windowsadmin.info

What does MT say? No transport rules? Tried sending to the DL in online mode? Does the user always get the email or occasionally if sent to the DL? Sukh

1. MT doesn't have an ifo 2. No transport rules 3. The message sent through outlook only 4. Always gets emails while send to DLRegards from www.windowsadmin.info | www.blog.windowsadmin.info

Many members in the DL? Checked corrupt rules? Possible to create a new DL with same members and test? Possible to remove each member one at a time and test email? What does the message header say? Any clues where it has come from? Sukh

1. How I can check corrupt rules through EMC? 2. The organizational policy doesn't allows to create and test new DL 3. The DL contains so many users and that mayn't be much easier 4.

Hi, The issue has been experienced while sending from multiple senders to the particular DL. Thus, I suspect this issue may related to DL. It's not a Dynamic list too.Regards from www.windowsadmin.info | www.blog.windowsadmin.info

You wont be able to find te corrupt rukes via the EMC, you will have to follow the KB mentioned by Xiu, however, if there are a number of users this may be time consuming. Have you tried to dump the DL members as per KB by Xiu? What if you look in ADSIEdit and check the members status of the DL? Is the user listed there? I suspect it's the same issue if sending via OWA? Sukh

Hi, I have checked rules corruption and it's okay. ADSIEdit ran and it's also perfect.Regards from www.windowsadmin.info | www.blog.windowsadmin.info

Hi, Please update here for the other questions in my post. Thanks. Xiu

Hi, Please try to force GC/DC replicate and then check the issue again.

Hi Xiu, The issue still exists. There re no replication issues as it's a matter of a single mailbox. We are using Exchange 2K7 with SP2. Is this because of old files?Regards from www.windowsadmin.info | www.blog.windowsadmin.info

Hi, Sorry for the late response. I just suspect it could be a cache related issue. So I recommend you to use new account to send email to DL again and then check the issue again. Besides, please check if delegation has been set for that user. Xiu
