Duplicate Sensitivity Label Headers and Footers showing in Outlook emails

Ian Clarke We have a similar issue, we are using a signature tool, in pilot, where emails are passed to a cloud provider to apply the signature and return the email to then be sent out.  This back and forth is done with a mail connector to the signature provider.  We also use Information protection labels,  setup to add a footer, but even as a header the behaviour is the same. What we have found is the label is applied as the email goes to the signature provider, and again when the email is returned to be sent out.

So basically the recipient of the email see's the below, if Information Protection Purview label is configured as a footer.

<FROM>

<TO>

<Subject>

<Email body>

<Signature>

                                                  Classification: Private

Or as a header recipient see this behaviour.

<FROM>

<TO>

<Subject>

I've logged a support case with Microsoft and have reported back that it's a bug.  I do hope they fix soon
