Hi Lydia Martin,
Welcome to Microsoft Q&A.
Sorry for this frustrating experience regarding the Mendeley Cite plugin in Microsoft Word for Mac (v19.99.1) issue. To resolve this, here are some troubleshooting steps you can try:
1. Fix Citation Insertion Failures
Update Software:
- Ensure Mendeley Reference Manager and Word are fully updated (check for updates in both apps).
- Use the latest macOS-compatible versions.
Reinstall the Plugin:
- Quit Word and Mendeley.
- Open Mendeley Reference Manager.
- Go to Tools → Install MS Word Plugin.
- Restart Word and check the References tab for the Mendeley toolbar.
Reset Word Add-ins:
- In Word, go to Word → Preferences → File Locations.
- Note the path for Startup (usually
~/Library/Group Containers/UBF8T346G9.Office/User Content/Startup/Word
). - Navigate to this folder in Finder and remove any Mendeley-related files (e.g., Mendeley Cite.pkg, Mendeley Cite.dotm).
- Reinstall the plugin via Mendeley (as above).
Repair Office Installation:
Use the Microsoft Office Reset Tool or reinstall Office via Microsoft AutoUpdate (in Applications).
2. Fix Font Mismatch in Citations
Modify Mendeley's Style:
- In Word, go to References → Mendeley Cite → Citation Settings → Change Citation Style.
- Select your style (e.g., APA) → Edit Style.
- Adjust the font settings under Bibliography and Citations to match your document.
- Save the style with a new name and apply it.
Edit Word Styles:
- In Word, open Styles (press ⌘ + Option + Shift + S).
- Right-click Mendeley Bibliography → Modify.
- Set your preferred font and formatting (match document font).
- Repeat for Mendeley Citation.
3. Stop Citations Changing When Editing Online
Avoid Online/Web Editing:
Mendeley plugins are not fully compatible with Word Online. Edit documents only in the desktop app.
Refresh References:
- After reopening the document in desktop Word, click Refresh in the Mendeley toolbar.
- If citations corrupt, Unlink and Relink your Mendeley library: References → Mendeley Cite → Settings → Unlink Library → then Link Library.
Prevent Sync Conflicts:
- Disable auto-save in Word (File → Options → Save → uncheck AutoSave) while working offline.
- Use OneDrive sync only after closing the document.
Advanced Troubleshooting
Clear Word Cache:
- Quit Word.
- Delete the Word cache folder:
~/Library/Containers/com.microsoft.Word/Data/Library/Caches/.
- Restart Word.
Recreate the Document:
- Create a new Word document.
- Copy/paste your content (without citations).
- Reinsert citations fresh.
Check for Conflicts:
- Disable other Word plugins via Word → Preferences → File Locations → Add-ins.
- Test with only Mendeley enabled.
Verify System Compatibility
- Ensure your macOS version supports both Word and Mendeley (e.g., macOS 12+).
- Use Rosetta for Intel-based plugins if on Apple Silicon (M1/M2): Right-click Word → Get Info. Check Open using Rosetta.
