Up until a few weeks ago, email sent out using an account set up for all users to send as, could recieve delivery notifications just fine. Now, without apparent cause, this has stopped. However, if a user sends the email as themselves they receive the status messages just fine.A brief background, the generic account is set up so any user can send as the generic account. When messages come into the generic account, they are forwarded to a distribution group. Only read receipts will function as of a few weeks ago.If a user sends as themselves, the delivery notification, and read receipt will come in fine- as expected. I have checked my connector settings, and since the users are receiving notifications otherwise just fine, I am to assume they are correct and unchanged.There were a number of unanswered posts on this, I am just hoping someone has made headway.

Issue description:Read Receipt isnt working for a user account when other sends as this account 1. Which version of exchange do you use? Please describe the topology 2. Please login that generic accounts mailbox, try to reproduce the issue in its own mailbox 3. Please check ifRead Receipt has been triggered by using Messaging Tracking Center 4. If Read Receipt shows that has been delivered to generic account, please disable all rule on the generic account temporarily to check the issue

Please also try to create a test account and Send As it as testing, see if the issue only persists on the generic account

Do a message tracking and check if the read receipt is actually getting to the DL or not.
