However, the changes aren't saved to the server until the conflicts are resolved. All changes in the document are saved on your computer in the Microsoft Upload Center, even when the document contains conflicts. When edits conflict, you must resolve them before you can save the document to the server. Conflicts can occur when one person works offline and then saves the document to the server, or when two people work on the same part of a document and save to the server before refreshing the document with updates made by other authors. When multiple authors are collaborating on a document, they might make changes that conflict with one another. In the Delete drop-down list, select Delete All Comments in Document. You need to remove comments separately from tracked changes. Right-click the change and select the option to accept or reject it. When you accept or reject a single change, Word will not move to the next change in the document. Tip: To review changes in the document without accepting or rejecting them, select Next or Previous.
