Box Drive Migration Broke Microsoft Word/Outlook Box Integration on Mac - Word Still Opens Archived Box Sync Folders from Migration Date

Hi everyone,

I'm hoping someone has run into this after migrating from Box Sync to Box Drive on macOS.

Environment

  • macOS
  • Microsoft 365 / Word / Excel / Outlook for Mac
  • Box Free account
  • Migrated from Box Sync to Box Drive on July 6, 2026

What I'm Seeing

After uninstalling Box Sync and installing Box Drive, Box created:

  • Archived - Box Sync
  • Box Sync (backup)
  • ~/Library/CloudStorage/Box-Box

The issue is that Microsoft Office still appears to be referencing the old Box Sync data.

Evidence

  1. Box Drive works correctly

    • Creating a folder in: 
      ~/Library/CloudStorage/Box-Box
      immediately appears on Box.com.

  2. Word can open files from Box-Box

    • Documents stored in Box-Box show up under Word's Recent files list.
    • The path shown in Recent is: 
      Macintosh HD > Users > rs > Library > CloudStorage > Box-Box

  3. Office's Box integration appears broken

    • In Word, when I choose Manage Storage Accounts → Box, I receive:

      "Box for Microsoft Office (Desktop) is currently disabled by your Box administrator."

  4. The built-in Box location is stale

    • Whenever I browse the Box location from Word/Excel/Outlook, I see folders and files dated July 6, 2026 (the migration date).
    • These appear to be coming from the archived Box Sync location rather than my current Box account.

  5. Box Integrations page

    • Box Drive = enabled
    • Box for Microsoft 365 for Web = enabled
    • Box for Office does not appear connected in the same way
    • Attempting to install Box for Office from Box's integrations page downloads BoxForOffice.exe (Windows installer) even though I'm on a Mac.

Main Question

Has anyone successfully reconnected Microsoft Office for Mac to a Box Drive-based installation after migrating from Box Sync?

Specifically:

  • How do I remove the stale Archived - Box Sync reference from Word/Excel/Outlook?
  • How do I get Office to browse the actual Box Drive / Box-Box location rather than the old migration archive?
  • Is Box for Microsoft Office (Desktop) still supported on macOS, or is Box Drive now the only supported workflow?

Any guidance would be appreciated. I have approximately 20 years of files in Box, so I'm being very cautious about removing old Box Sync references without understanding exactly what they do.

Thanks!
