Here comes the question: how do you unprotect a Word document? But sometimes the protections can cause problems for you when you're trying to open or edit a protected document without knowing the password. These protections can be very useful when you want to keep the content of the document private. You can also restrict editing on the document, meaning that someone can only read the document but they can't modify it in any way. You can lock a Word document by setting a password so that someone can't access the document. But as easy as it is to share and collaborate on a Word document, Microsoft has also included features that are meant to restrict the number of people who can collaborate on a document. A single Word document can be edited by multiple people, with each person's edit clearly marked, making it very easy for users to collaborate on a single project.

Downgrade your Word to version 16.If you use Microsoft Word a lot, you may already be aware of various options you have in document sharing.Although, this has not been confirmed by the developers and isn't working 100% of the time, it's still worth a try: In the meantime, we have devised a set of steps that can somehow help and prevent this error. Rest assured that this has already been reported to the relevant team for further action. That having said, this plugin error appears specifically in MacOS Mojave with versions 16.20 and 16.21 for Word. Even if an OS is not supported, Mendeley Desktop might still operate to a satisfactory level on it however we might not be able to offer full support or fixes for any issues. Please be informed that at the moment, Mendeley Desktop isn't supported in Mac OS 10.14 (Mojave).

Thank you for contacting Mendeley Support and for bringing this to our attention.
