Overview
When a sender from outside your organization sends an email that includes a read-receipt request, an automatic response is sent out from the server as soon as GFI Archiver collects the email from the journal mailbox for archiving purposes.
This response informs the sender that the message was deleted before it was read. You can follow the solution in this article to remove the headers from emails received by the journaling mailbox when it is hosted on Microsoft 365 (previously known as Microsoft Office 365) so the sender doesn't assume that their message was deleted without being read. Please note that this transport rule only works for external senders.
