Marking as Reserved
You can reserve a document or file to alert other users you're working on it. This doesn't lock the document, but it alerts other users that you are planning to update the item.
Reserving documents is especially useful if you're using uploaded files, but can't use the Jive for Office. The Reserved badge doesn't prevent anyone else from editing, but it shows information about who is working with the item, making it easy for other people to check in with you before adding their own edits. For more information, see Reserving files and documents.
