    Hi Catherine,

    Surely I can help you.

    Open Word > top menu > Word > About Word → shows if Activated.

    If activation fails, Mac shows “Activation Required” or asks to enter product key / sign in again.

    Let me know if the activation required is seen or if the activated product.

    1. Open Keychain Access → search “Office” → delete items like Office Activation, ADAL, MSOffice…
    2. Go to ~/Library/Containers and ~/Library/Group Containers → delete these folders if present:
      • com.microsoft.Office365ServiceV2
      • UBF8T346G9.Office
      • UBF8T346G9.ms
    3. Restart Mac → open Word → Sign in with the same Microsoft account that has the subscription.

    I’m eager to hear back and work together to find a solution.

    On macOS with a Microsoft 365 subscription, common reasons Word will not save documents include:

    1. AutoSave disabled because of file location or format
    • AutoSave only works if the file is stored in OneDrive, OneDrive for Business, or SharePoint Online and is opened via File > Open from that cloud location.
    • If the document is stored locally (Mac folder, file server, on‑premises SharePoint) or in an older format such as .doc, AutoSave is disabled and changes may not be saved automatically.
    • To fix this, save the file as a modern format (e.g., .docx) into OneDrive or SharePoint Online, then reopen it from File > Open and confirm AutoSave can be turned on.
    1. File or location not supported for AutoSave AutoSave can be disabled for several reasons:
    • The file is in an older format like .doc.
    • The file is embedded inside another Office file.
    • The file is stored in a local OneDrive folder while OneDrive sync is paused.

    For Excel specifically (similar principles apply to Word/Office behavior):

    • Remove password encryption if present: Review > Protect Workbook, clear the password, select OK.
    • Remove restricted access: File > Restrict Permissions > No Restrictions.
    1. OneDrive Files On-Demand issue (if saving to OneDrive)
    • Large Office files saved on a PC with OneDrive Files On-Demand enabled could fail to save without error. This issue is documented and marked as fixed.
    • Ensure the latest Office updates are installed: open any Office app and go to File > Account > Update Options > Update Now (on Mac, use Help > Check for Updates in Microsoft AutoUpdate) so that the OneDrive/Office save issue is resolved.
    1. Word/Office not fully updated
    • Some save issues are resolved by installing the latest Word/Office updates. After updating, quit Word completely and reopen it, then test saving a new document and an existing one.

    If Word still will not save after these checks:

    1. Create a new blank document, type some text, and save it to a local folder (e.g., Documents). If this works, the problem is likely with a specific file or location.
    2. Move the problematic document to a different folder or drive and try again.
    3. If the issue only occurs with cloud locations, verify OneDrive/SharePoint sign‑in and sync status, then reopen the file from File > Open.
