Right now you cannot search for administrative Event regarding Unified Labeling in Office 365 Admn portal Audit Log Search.

Include Visio in application support for labeling and protection (in addition to the existing support for protection).

Currently Mail Merge with mandatory classification, forces users to classify every single email that is sent by the mail merge, even when the users have correctly classified and saved the Word document template. This is causing our users to manually classify every single mail sent in a mailshot. Default classification won't help in the case that there's a requirement for a mailmerge to be a different classification. WE don't want to manage an operational overhead of having scoped groups with passphrases to get around the issue - please can you get AIP classifications working with mail merge.

Currently, when you attach an unprotected Office document or PDF to an email, and then protect the email, the attachment inherits the protection. This should be expanded to include other file types.

When users export, save as or print (e.g. to pdf file) a document that has already a classification (or protection) label, the destination file should keep the same classification label and protection of the source file.

Provide a client and admin view of document classification, labeling and protection history

Enforce an anti-tampering mechanism (such as the client having a hash of the label and knowing if it was changed) and log centrally for reporting.

Using senstivity labels to classify emails I would like to be able to see the label for each email in my inbox in order to sort or find unclassified emails.

Add new options for expiring labels (removal and/or replacement) based on time, approvals to make changes and notifications on change.

Different people have different needs for the default label depending on their day to day job.( working in finance : default = confidential ; working in external communication default = unrestricted)

We liked that users can choose the better appropriate default label . If not possible apply default label to scoped policy (so to users groups).

Integrate the possibility to use image-files (such as: gif, png or jpg) for labeling as footer, header or watermark. The would be a great feature for some customers, so it is possible to support the corporate identity with specific colours and embedded graphics.

Would like enhanced multi-language support for visibility markers within Office 365 documents that use Azure Information Protection.

Currently visibility markers only display in one language

Today, when a CSV is protected we protect it as .csv.pfile. This is an ask to natively support CSV files with .pcsv

Currently, it is not supported to excute Get-AIPFileStatus /Set-AIPFileLabel command on SPO libraries.
We would like to use these commands on SPO libraries the same as On-premises SPS.

Apply/update the markings inside the document when right click on a file and apply label or the label is changed, and when the scanner autoclassifies a document.

In special customer scenarios, systems might be completely disconnected and not have direct or indirect access to the cloud service. This is supported in the AIP Classic client. We need an option to distribute the policy manually in the disconnected environment and for protection we need HYOK integration. To enhance the experience (compared to the classic client), bootstrapping the client automatically would really help.
Even if this is some kind of niche scenario, it might be important for many public sector or highly regulated customers.

Microsoft Project supports sensitivity labels for classification, labeling and protection

Provide functionality to allow for formatting and hyperlinks in an label description. This would allow for when a user hovers over a label in the toolbar, a clickable link is available to them - to take them to the organization's classification or GDPR compliance policy, for example.

When a label places the visual marking on an excel spreadsheet, page breaks appear. Users find this disturbing and tedious to remove on each spreadsheet.
