The above article should answer your question. In summary, if you delete a sensitivity label (with encryption) in Microsoft 365 Compliance Center, depending on how you open the document (Desktop apps or Office on the web), you will not see the previously applied label, and the document may no longer be protected by the encryption.

hi folks in the community
I have been playing with AIP recently, a few things that I can't get my head around with. after labeled a document in word. then I decided to delete all the labels in the compliance center. Then the documents say no label found. I was a bit confused. what happened behind the scene and why the document seems not "protected"
regards
