Microsoft Outlook Plugin for Alfresco 5.2 from EisenVault Document Management (https://eisenvault.com). This allows one-way communication - i.e. saving of emails and attachments from Outlook to Alfresco. It has been tested with Outlook 2010, 2013 and 2016 on Windows 7, 8.1 and 10. It is compatible with Alfresco Community 5.2 DMS as it uses the 5.2 REST APIs. It doesn't work with older versions of Alfresco DMS.
