Collaborative authoring with Microsoft Office™ allows multiple users to edit an Office document at the same time using the Office desktop software, Office Online™, the Office mobile apps, or in a browser. Only users with Edit and Download permissions for a document can edit the document with collaborative authoring. Collaborative authoring can be used with Microsoft Word™ (*.docx), Excel™ (*.xlsx), and PowerPoint™ (*.pptx) documents.
Collaborative authoring connects Vault to the Office 365™ server and uses it as a work area for collaboration sessions. Your organization must have an Office 365 tenant to use collaborative authoring.
For additional information, see Configuring Collaborative Authoring with Microsoft Office and Using Collaborative Authoring with Microsoft Office.
Note: Collaborative authoring with Microsoft Office is not the same as checking out to Office Online.
