Word on my mac does not allow to save a document, with the message that there is not enough space on drive, when there is ample space left.

    Dear @Tatakis, Dimitris,

    I hope you’re having a good day. 

    Thank you for posting your question.

    Based on your description, it may not actually be a storage-capacity issue, especially if your Mac still has plenty of free disk space available.

    To help narrow down the cause, could you please let me know:

    • Does this happen with all Word documents or only a specific file?
    • Are you saving the file locally on your Mac, or to OneDrive/SharePoint?
    • Are you able to save new Word documents successfully?

    In the meantime, I would recommend trying to save the document to a different local folder (for example, your Desktop) using Save As, and also testing with a brand-new Word document.

    The results of these tests will help determine whether the issue is related to the document itself, the save location, Word, or macOS permissions.

    I hope this helps. Please feel free to share the results of these checks, and I'll be happy to help investigate further.

    Please understand that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.   

    Warm regards,

    This usually happens when Word cannot complete its temporary-file save process, even if the Mac still has free space. On Mac, Word creates a temporary file during save or AutoSave, and if that process is interrupted by the environment, Word can show disk-space or serious disk error messages.

    Try these steps in order:

    1. Update Office for Mac
      • Open Word.
      • Select Help > Check for Updates.
      • Set updates to Automatically if available.
      • Select Check for Updates and install any available update.
    2. Save to a different location
      • In Word, select File > Save As.
      • If needed, click On My Mac.
      • Save the file to a different local folder such as Desktop.
      • If the file is currently being saved online, switch to a local location first.
    3. If saving to OneDrive or SharePoint, try a local save first
      • Use File > Save As.
      • Change the save location to local storage, save the file, then move it back later if needed.
      • If the file is being saved as PDF to an online location and changes back to .docx, change the extension to PDF or save locally first, then switch back to OneDrive.
    4. Check the file name
      • Remove invalid characters from the file name if present.
      • Invalid characters include: <, >, /, \, :, |.
    5. Check whether OneDrive files are taking local disk space unexpectedly
      • On Mac, Always keep on this device files do take up space.
      • Online-only files do not take up space until opened.
      • If needed, in Finder, right-click large OneDrive files and select Free up space.
    6. If the error continues
      • On Windows, Microsoft notes this can also happen when available disk space is consumed by the page file or by antivirus software behavior. The Mac article specifically recommends updating Office first, then contacting support if the problem continues.
