Edit Local Files in Office Online

Enable online editing for Word, Excel, and PowerPoint files while keeping them stored securely on your servers. No need for a VPN, syncing, or a desktop Office installation. Users can seamlessly edit Office files hosted on your Windows file servers, NAS, S3, or Azure Files. All while maintaining on-prem security with AD or Entra ID permissions.

MyWorkDrive lets users edit and co-edit Office files in a browser while keeping data on your servers, either via Microsoft 365 (OneDrive or SharePoint), your own Office Online Server, or with OnlyOffice.

Why This Matters

Legacy Systems
  • Traditional options for editing files from outside the office create friction.
  • VPNs are slow for large files and expand your attack surface, increasing the risk of cyberattacks.
  • Sync-and-share tools copy data around and create version chaos, confusion, and data sprawl.
  • Requiring desktop Office everywhere adds licensing and device management overhead.
MyWorkDrive + Office Online
  • With MyWorkDrive and Office Online, users can open and coauthor files in a browser while the files remain on servers.
  • You get fast collaboration, full control, and less software to manage on endpoints.
  • Eliminates the need to download files or rely on third-party cloud storage. Data stays secure and compliant on your infrastructure.
  • Seamlessly integrates with existing Active Directory and NTFS permissions, reducing administrative overhead.
