DocuWare can be added to Microsoft Outlook in two ways:
Roll out for the entire organization: A Microsoft organization administrator deploys the add-in through Microsoft Admin Center, either to all employees or to specific users within the organization. This method is recommended to keep the deployment process as simple as possible and is supported for both DocuWare Cloud and on-premises systems.
User install the add-in manually: In DocuWare Cloud only it is also possible for the users to install the add-in for their own account. In this case, the administrator must approve the app after the user has installed it.
