Users experience an issue where Word Online fails to auto-save and locks the document from editing after opening the Mendeley Cite add-in.

How to Fix Word Online Auto-Save Errors with Mendeley Cite

Product: Word Online, Mendeley Cite
Device & OS: Multiple operating systems
Scenario: Adding citations and references to a document using Mendeley Cite within the Word Online web interface.
Observed behavior: Word Online displays an auto-save error message and the document becomes completely uneditable shortly after the Mendeley Cite panel is launched.

Before you start

Before attempting any fixes, manually download a copy of your current document to your local hard drive (File > Save As > Download a Copy) to prevent data loss due to the auto-save failure.

Solution 1Recommended

Clear Browser Data and Update the Add-in

Clearing out corrupted browser cache and ensuring you are running the latest version of Mendeley Cite can resolve cloud syncing conflicts.

Because Word Online relies heavily on your web browser's storage capabilities to manage real-time auto-saving, corrupted cookies or an outdated Mendeley Cite add-in can interrupt this process and lock the document.

Update Mendeley Cite

Open Word Online, navigate to 'Insert' > 'Add-ins', and check the Office Store to ensure your Mendeley Cite add-in is updated to the latest version.

Clear Browser Cache

Access your web browser's settings (e.g., Chrome Settings > Privacy and security), select 'Clear browsing data', and clear your cache and cookies.

Disable Conflicting Extensions

Temporarily disable other browser extensions (especially ad-blockers or other citation managers) from your browser's extension manager to prevent background conflicts.

Restart and Test

Refresh your Word Online tab, launch Mendeley Cite again, and type a few words to verify if the auto-save status updates successfully.

Clear Browser Data and Update the Add-in

Contact Support: If the issue persists across different browsers, you may need to contact Microsoft or Mendeley support directly, as this could be a known service outage.

Solution 2

Edit the Document in the Desktop Word App

Bypassing the web browser and using the desktop application provides a more stable environment for heavy add-ins.

Frequently Asked Questions

Why does Mendeley Cite stop Word Online from auto-saving?

This typically occurs due to a syncing conflict between the add-in's background scripts and Word Online's continuous cloud saving. It is frequently exacerbated by outdated browser caches, cross-site tracking blockers, or conflicting browser extensions.

Will I lose my work if the auto-save error appears?

Yes, if the document becomes uneditable and the auto-save indicator shows an error, any changes made since the last successful sync may not be saved to the cloud. You should immediately copy your recent text or download a local copy of the file.

Does Mendeley Cite work better on the desktop version of Word?

Generally, yes. The desktop application allocates system resources more effectively and does not rely on browser cache, making it much more stable when running resource-intensive add-ins like Mendeley Cite.

How do I isolate conflicting add-ins in Word Online?

Go to 'Insert' > 'Add-ins' in your Word Online ribbon, click on 'My Add-ins', and systematically disable other active add-ins. Reload the document to see if Mendeley Cite functions properly without them.
