# Locks Office Documents For Exclusive Editing

Your users may prefer working with Office documents in an *exclusive* mode, that is, only the user that first opened the document has exclusive editing rights over the document. If another user opens the document, it will open for read-only. This is the default behaviour when working with Office documents on a network file server.

When starting a new <code class="expression">space.vars.PRODUCT\_NAME</code> subscription, *exclusive editing* is the default behaviour when opening Office documents from your <code class="expression">space.vars.PRODUCT\_NAME</code> network drives.

On opening a document in Office, <code class="expression">space.vars.PRODUCT\_NAME</code> acquires a SharePoint lock on the document preventing other users from opening the document for editing.

<code class="expression">space.vars.PRODUCT\_NAME</code> maintains the lock on the document for the duration the document is opened from <code class="expression">space.vars.PRODUCT\_NAME</code>. On closing the document, the lock is released, allowing another user to open the document for editing.
