I am trying to upload a word .docx file that is password protected to include in a campaign email and I am receiving an error in the upload to the library saying the 'file extension does not match the file format'. If I take the password off it works fine.
I apologize for any issues with the upload process of your Word document. When a file is uploaded to the library for public distribution, it needs to remain accessible so recipients outside of your local computer can access the document. Documents with passwords or special encryption cannot be imported into the library because the extra level of security is not recognized by our system. I will certainly pass feedback to our developers about allowing encrypted documents in the future though I am sorry for any inconvenience this may cause.
