Turn off commenting on PDF

[lauraa18658182]

Does anyone know how to turn off the commenting on a shared PDF? I share PDFs with my team (through a link) and ask them to leave comments, but I give them a deadline. They don't have Adobe accounts so they leave the comments as guests. I want them to still be able to view the PDFs and the comments after the deadline, but don't want them to add additional comments. Right now the only option I can find is unsharing the file, which would remove their access to the document. Does anyone know of a way to just turn off the commenting but keep the PDF shared? Thanks!

You can apply a security password that allows opening the file but not modifying it, such as adding comments to it.

You will need to have Acrobat to do it, though.
