I have not received any forwarded email since 29 September and am now receiving failure messages regarding emails sent from my work address to my forwarded address since 29 September.
Happy to send bounce messages to you if you provide an email address.
The first couple of lines (typical) are:
=========================
<<my forwarded email address>> An error occurred while trying to deliver this message to the recipient's e-mail address. Microsoft Exchange will not try to redeliver this message for you. Please try resending this message, or provide the following diagnostic text to your system administrator.
The following organization rejected your message: [54.68.4.223].
Diagnostic information for administrators:
Generating server: <<my employer's email server address>>
We are investigating this issue now. It seems our delivery attempts are resulting in an error which we have not yet worked out. We will let you know as soon as we have an update for you.
In the meantime, selecting a new destination address would get email forwarding again.
