    • Enable versioning in DocumentLibrary for each user’s My Site. Ensure that you enable both Minor and Major versions.


      For more information, refer to the sample scripts attached to this document for auto-provisioning My Site and enabling versioning.

    The Office Web Apps 2013 configuration is specific only to SharePoint 2013 on-premises environment.

  • Create the OneDriveOnPremHost registry key.

    Location: HKEY_LOCAL_MACHINE\Software\Interwoven\WorkSite\8.0\Common\Options

    or for iManage Work 32-bit installation on 64-bit operating systems:

    Type: REG_SZ
    Value: <On-premises location>
    Example: http://sp2013:1080/

All co-authoring activity is managed by SharePoint technology. Office 365 sites use OneDrive for Business, which leverages SharePoint technology to support co-authoring. On-premises deployments use SharePoint directly. For more information, visit the following web pages:

If a OneDrive sync client is available on the users' machines, they see OneDrive as a storage location. To prevent the use of OneDrive for sharing documents, it has to be removed manually. This prevents OneDrive from appearing again elsewhere, such as, in the Word app on iOS as a storage location.

For more information about removing OneDrive, visit the following web page:


In both on-premise and online OneDrive, administrators can monitor the MySite sites for content. Co-authored documents are saved to MySite\Documents\imPortable\<Database>\<User>\DocName_DocNum. Documents in any other location are not part of co-authoring.

Alternately, you can block access to OneDrive from Office 365. For more information, visit the following web page:


  1. Close all Office apps, iManage apps, and Adobe apps.

  2. Uninstall any previous versions.
