Hi,
We are looking to restrict copy functionality in WOPI Excel read-only modus. We tested and found that the ‘ProtectInClient’ currently works on WOPI production which blocks copy for end users. However, the available documentation on this property seems to be contradicting.
This property is currently listed without any remarks at: https://docs.microsoft.com/en-us/openspecs/office_protocols/ms-wopi/4b1d38ff-0d6a-42e4-8901-175b3c3c5890
Looking at the documentation on wopi.readthedocs.io the property is listed under the unused and future properties:
https://wopi.readthedocs.io/projects/wopirest/en/latest/files/CheckFileInfo.html?highlight=protectinclient#term-protectinclient
Can we safely use and rely on this spec to be working on WOPI production?
Also, is there an ETA on the ‘CopyPasteRestrictions” property as pointed out in readthedocs and will this replace the ‘ProtectInClient’ property in the future?
