So there can be situations where in the Current Username (at the time the file is opened) is not needed within Content Marking for a given Label but rather the "Created By" or "Last Modified By" would be more useful.

When a DLP alert is raised, the privacy team will work on resolving the alert and in this process will need to view the contents of actual message. Communication compliance (CC) solves this, but there is no correlation with DLP alert. The message can be looked up in CC by sender, date, subject and so on, but it would be great to have a clickable link to the message in CC in the DLP alert.

to set justification question for the following scenario only:

if he moves from confidential to internal or public
not if he moves from internal to public

So from confidential to internal or public ( ask justification)
From internal to public ( no need to justification)

It would be good if you can configure the permissions for the creation of sites in sharepoint, and only those that are within a specific group can do so

As you can see, if click "Protect" tag on Office, there is appeared "custom permissions".
https://docs.microsoft.com/en-us/azure/information-protection/rms-client/client-classify-protect#set-custom-permissions-for-a-document

When I clicked "sensitivity" tag on office, there isn't appeared "custom permissions".
I want it to display "custom permissions" in the future.

In the latest AIP UL client (preview), it's possible to revoke access on a protected document. But if offline access is allowed, users will continue to be able to access the documents that have been revoked until the offline policy period expires.
I would be more convenient that revoking applies directly for users trying to open a copy while ONLINE.
The current behavior may force us to remove offline access (or reduce dramatically the period) on labels of great sensitivity. Still our end-users, especially top managers would need such offline mode

When searching keywords with two-byte characters, search experience will be diminished. Please improve the Outlook search experience better.

Two pages with SIT definitions exist. It is unclear which one applies when/where.
https://docs.microsoft.com/en-us/exchange/policy-and-compliance/data-loss-prevention/sensitive-information-types?view=exchserver-2019#netherlands-citizens-service-bsn-number

https://docs.microsoft.com/en-us/microsoft-365/compliance/sensitive-information-type-entity-definitions?view=o365-worldwide#netherlands-citizens-service-bsn-number

Please add an URL on the portals in places where the sensitivity information type can be selected referring to the correct applicable version of the docs (better yet - consolidate the two sets of SITs)

Currently it is not possible to create a digital signature on a Microsoft file that is protected. In order to sign a document in Adobe sign, the protection needs to be removed before creating the digital signature. After the digital signature is made, it is not possible to protect the PDF with a Sensitivity label. The solution should be that it is possible to digitally sign a protected file and/or protect a PDF that is digitally signed with Adobe sign.

Allow custom branding to work encrypt email that has first passed through external DLP system with update to email header marked for encryption with OME and add custom branding template to email.
Currently it does not seem like custom branding is working with emails that have been updated by external DLP that has updated the header.

Right now MAC does not have an easy option to check the owners information with Native experience and this is once of the most demanded ask by our users.

Yammer seems to have gone for AIP. All links for AIP Yammer at MS do not work anymore

Allow for mandatory labels in Office Online apps. currently a new doc can be configured to have a label, but the user can remove this.

Not sure that this is correct location but:
I would like to see the content of an email scanned for DLP/Sensitivity labels upon send. This would then match the behavior of the local Outlook app when UL client is installed

User can tag sensitivity label using Office app but there is no way to do so for PDF file on mobile. If possible maybe allowing users can tag PDF from email or OneDrive??

to be able to paste information from Excel documents to Powerpoint, when the Excel document is with Sensitivity Labels applied, where the document is encrypted. Currently, the specific paste that cannot be done is to attach information from Excel as a link / image, where, once the Excel information is modified, it is reflected in Powerpoint

The applied sensitivity label is set to NOT allow copy/cut of data within a document. This works as expected with Office desktop applications, but Office Online allows copying and cutting.

After applying a sensitivity label to a document, the print option is greyed out in Office Online.
Even if the sensitivity label is set to allow the logged in user to print.
