Cloud storage has become essential in modern productivity, and Microsoft’s OneDrive integration offers a seamless way to save, share, and access documents across devices. But what happens when OneDrive fails to sync with Microsoft Office for Mac 2016?

If you’ve encountered issues like:

  • Office files not uploading to OneDrive

  • Sync delays or “upload pending” messages

  • Missing changes across devices

  • OneDrive folders not appearing in Office apps

You’re not alone. In this guide, we’ll walk you through proven steps to identify, troubleshoot, and fix OneDrive sync issues with Office 2016 on Mac.

Why OneDrive Sync May Fail with Office 2016

Several reasons could prevent syncing from working smoothly:

  • Outdated Office or OneDrive version

  • Connection or authentication issues

  • File path or name incompatibilities

  • Sync conflicts or locked files

  • Corrupt cache or installation errors

  • macOS permission issues

The fix depends on the root cause, which we’ll help you identify and resolve.

Step 1: Check Office and OneDrive Compatibility

Office 2016 for Mac and OneDrive are compatible, but updates are crucial for stable operation.

✅ Ensure You’re Running the Latest Office 2016 Update:

  1. Open any Office app (Word, Excel, etc.)

  2. Go to Help > Check for Updates

  3. Update using Microsoft AutoUpdate

✅ Update the OneDrive App:

  1. Open the App Store on your Mac

  2. Search for OneDrive

  3. Click Update if available

Note: Microsoft ended mainstream support for Office 2016 in October 2020, so newer OneDrive features may not fully integrate.

Step 2: Sign Into the Same Microsoft Account

Office and OneDrive must use the same Microsoft account for syncing to work.

How to Check:

  1. Open Word or Excel

  2. Click Word > Preferences > Accounts

  3. Ensure you’re signed in with the same email used in the OneDrive app

  4. In OneDrive, go to Settings > Account tab and verify the login

If you’re logged into different accounts, OneDrive won’t recognize Office save locations.

Step 3: Confirm OneDrive Folder Location and Sync Status

OneDrive creates a local folder that mirrors cloud files. If Office doesn’t recognize this folder, syncing fails.

Check the Folder:

  1. Open Finder

  2. Click OneDrive in the sidebar

  3. Open your Documents or shared folder

  4. Check if:

    • Files are syncing (look for green checkmarks)

    • Office files (.docx, .xlsx) are present

    • You can open and save a test document

If not, continue with the troubleshooting steps below.

Step 4: Save Files Directly to OneDrive

Instead of saving locally and moving files, save them directly to OneDrive from Office apps.

How to Save to OneDrive in Office 2016:

  1. Open Word, Excel, or PowerPoint

  2. Go to File > Save As

  3. Choose OneDrive – [Your Name]

  4. Select a folder within your OneDrive

  5. Click Save

If OneDrive is missing from the Save As menu, the app might not be linked properly. Re-sign into Office.

Step 5: Reset OneDrive Sync (If Stuck)

If OneDrive is stuck or misbehaving, a full reset often resolves the issue.

How to Reset OneDrive on Mac:

  1. Quit the OneDrive app

  2. Open Terminal (search in Spotlight)

Paste the command:

 swift
CopyEdit
/Applications/OneDrive.app/Contents/Resources/ResetOneDriveApp.command

  2. Press Enter

  3. Restart OneDrive from Applications or Spotlight

This will reinitialize your sync settings. Your files will resync, but no data is lost.

Step 6: Check for File Name or Path Issues

Office 2016 may reject sync if:

  • File names have special characters

  • File paths are too long

  • Certain file types are unsupported

Fix:

  • Avoid characters like * ? < > | ” : / \

  • Limit file names to under 255 characters

  • Shorten nested folders (e.g., /OneDrive/Work/Project2025/Docs)

Step 7: Fix Permissions in macOS

macOS security settings can block Office or OneDrive from accessing necessary folders.

Update Permissions:

  1. Go to System Settings > Privacy & Security > Files and Folders

  2. Enable access for OneDrive

  3. Also go to Full Disk Access, and make sure Microsoft Word/Excel/OneDrive are checked

Restart your Mac to apply changes.

Step 8: Disable Office Upload Center (if active)

Office Upload Center can sometimes block proper syncing.

Disable It:

Office 2016 for Mac doesn’t include Upload Center like Windows, but if you manually installed upload helpers, remove them.

  1. Search for Upload Center using Spotlight

  2. If present, quit and remove from Login Items under System Settings

Step 9: Test with a New User Profile

Sometimes local user profiles get corrupted.

  1. Go to System Settings > Users & Groups

  2. Create a new user account

  3. Log in and open OneDrive and Office

  4. Test file sync from a clean slate

This helps determine if the issue is account-specific.

Step 10: Reinstall Office and OneDrive

If all else fails, perform a clean reinstall.

Uninstall Office:

  1. Close all Office apps

  2. Delete Office from Applications

  3. Remove residual files from:

    • ~/Library/Containers/com.microsoft.Word

    • ~/Library/Group Containers/UBF8T346G9.Office

Reinstall from Source:

  • Download Microsoft Office for Mac 2016 from your license provider (e.g., GameCardShop)

  • Reinstall and activate using your product key

Then reinstall OneDrive from the Mac App Store.

Bonus Tip: Use the OneDrive Web App as a Backup

If sync issues persist, you can always upload or edit Office files via:

🔗 onedrive.live.com

  1. Sign in with your Microsoft account

  2. Upload your files manually

  3. Open documents in Office Online

  4. Download or resave to local folders as needed
