Outlook for Mac users trying to open an attachment receive the following error: The file “filename.ext” couldn’t be opened because you don’t have permissions to view it.


The issue is fixed by installing the macOS 11.6.7 update.


If you haven't installed macOS update 11.6.7, you can work around this issue by closing the helper application. For example, if you are trying to open a PDF file that uses Preview as the default application, quit Preview first.
