#### message composition If I understand correctly, according to the reporter Outlook uses non-standard* header fields (MSIP labels) for confidentiality classification – not the standard `Sensitivity` header field, for which bug 353800 requests support. *I didn't find MSIP labels in [RFC 4021](https://www.rfc-editor.org/rfc/rfc4021) nor in its updates. Under *"expected results"* reporter requests to *"add the header described above"* (i.e. the non-standard MSIP labels) for message composition. The bug title says as much. However I would assume that if Thunderbird implements an email confidentiality classification, it will use the standard header field requested in bug 353800 rather than the non-standard approach requested here. #### message display On the other hand, as far as only message display is concerned, it could be nice-to-have (for enterprises) if TB were able to understand and display the Outlook confidentiality classification. (This is not explicitly what [comment #0](https://bugzilla.mozilla.org/show_bug.cgi?id=1741519#c0) requests, but the bug could be adapted towards that end?)
