We are using the exchange server 2016. Our users are working in POP3, so we are unable to take the backup for sent items. Because we are using the PST export option in Power Shell in exchange server. So we were planned to work auto BCC rule for every
user in the mailbox for the server. Those rules were working fine for the past year. But unfortunately, for the past three months, those rules are not working. But while we sending the email in the internal domain for TO, CC or BCC that rule was working fine.
But if while we sent the email for the external domain only it will not work. So I did delete all rules & recreated, but still, we are facing the same issue.so I decided to delete the username & recreated the same username but the problem wasn't solved.
So I am creating a new username, it was working fine. Please resolve my issue as soon as possible.
