Add marking to Outlook message subject as a prefix or suffix (configurable)
Allow for a configurable prefix or suffix to be added to the subject line of an Outlook message. For example - my message subject is "Testing" when I classify this as Confidential the subject line becomes "Testing [C]" adding in an abbreviated form of the classification for quick reference and visibility in the inbox.

Whenever a Sensitivity Label is created for Email it should be appended to the email subject.

Could we find a workaround to accomplish this using mailflow rules?

I want to configure an Exchange Online mail flow rules for Azure Information Protection labels. What I need is in email subject lines set up the subject automatically added to the end of the subject. e.g., Test Email [DLM=Sensitive] Test email is my subject and [DLM=Sensitive] should automatically add to the subject at the end

The Prepend is a real pain. Very difficult to sort by Subject, triggers for automation are impossible. This functionality needs to be deployed ASAP - like equivalent competitive products.

This would be amazing functionality to have and would allow us to move away from various third party solutions and solely rely on AIP.

It is possible to Prepend the subject of an email message with defined text. We use the Australian government standard of [DLM=Sensitive] etc. However, the issue is that every time the email is replied to or forwarded the current classification is added to the subject line so it is possible to have many of these in the subject line.
In itself, this is not a major problem, however it causes issues when trying to search for emails by subject as the subject always starts with [DLM=***] and the more an email has been forwarded/replied to, the more of these will be in the subject.Therefore, it would be great to have the option to appended rather than prepend to the subject line.

just a thought...if configurable prefix or suffix is out of reach at this point as minimum the option to add the classification label text would be a great addition.
currently we are using Exchange transport rules to do this and while it works well it is administratively tedious to create and maintain.
