A family of Microsoft word processing software products for creating web, email, and print documents.
Hi Lucie,
Sorry for the inconvenience it may have caused.
Currently, there’s no options for users to set restricted editing while co-authoring. To co-author a document, all co-authors must have full permission to access and edit the documents.
As a workaround, you can divide a Word document into several separate documents, and share only the documents that need to be edited with co-authors.
Besides, you can submit feedback to UserVoice, which is the official suggestion box for Word. Other users will also be able to vote on the same post so that it will increase the awareness coming from the related team. More votes will make the team more aware that this is a highly requested feature.
Appreciate your understanding.
Best regards,
Madoc
