I am trying to apply a sensitivity label with protection to a .doc file. The process does not report an error but I am unable to open the file after applying the label. This is what I see in MS Word:
The Azure Information Protection Viewer shows this:
I am a site collection administrator, I am not sure why I am unable to view these files. I have the same issue if I try to protect any of the non-native files such as .dwg -> .dwg.pfile. If I try to protect files such as .jpg -> .pjpg, the files open without any issues. If I use the AIP tool to protect these files, the files open without any issues.
Could anyone point me to what might be going on here? Thanks!
If the protection label has been created with the "Co-Author" permission, the issue is replicated. Creating a new label with the "Co-Owner" permission resolves the issue.
