Using MS Word for negotiating contracts

Using MS Word for negotiating contracts

Hi
Our customers want to use MicroSoft Word to edit/change the document received for review in the Zoho Contracts negotiation process. They can download the .docx file in track change mode, but they can't upload. Is there a way for our clients' legal teams to use MS Word for their editing?

Furthermore: our legal team also prefers to work with MS Word. How can they upload an edited document in the negotiation process?

Best
Thomas
