    On Mac, Save and Save As can stop working when Office falls into a licensing problem or when Excel cannot complete its temporary-file save process. The “Couldn’t refresh licence. Error code 44” message points first to an Office activation/licensing issue.

    Try these steps in order:

    1. Refresh the Office license
      • Open any Microsoft 365 app such as Word or Excel.
      • In the macOS menu bar, select About Word or About Excel.
      • Select More Info…
      • Select Refresh License.
      • Then fully quit all Office apps and reopen them.
    2. Make sure Office is updated
      • Open any Office app.
      • Select Help > Check for Updates.
      • Install the latest updates.
      • This is recommended for Mac save-related errors.
    3. Check whether Excel is in reduced functionality/read-only mode
      • Recent Mac Office issues can allow files to open and print but block edit, save, or create new files.
      • If that is what is happening, updating Office is the first corrective step.
    4. Try saving the workbook another way
      • File > Save As and use a new file name.
      • If that fails, save to an alternative drive or location.
      • Excel saves by creating a temporary file first, then replacing the original. If that process is interrupted, save can fail.
    5. Check common save blockers
      • Confirm the destination has enough free disk space.
      • If saving to a network or external drive, test saving to the local Mac drive instead.
      • Temporarily disable antivirus software, if present, and test again.
      • If the workbook is shared, make sure another user is not saving or locking it at the same time.
      • If the file path and name are very long, shorten them. Excel can show “Filename is not valid” if the full path exceeds 218 characters.
    6. Try a workbook recovery workaround
      • Move the sheets into a new workbook:
        1. Press Shift+F11 to add a filler worksheet.
        2. Select the first real sheet, hold Shift, then select the last sheet.
        3. Right-select the grouped sheets and choose Move or copy.
        4. In To Book, select (New Book).
        5. Select OK.
      • Then save the new workbook.
    7. Try a different file format
      • File > Save As.
      • Save as .xlsx or .xlsm instead of older .xls if applicable.
    8. If the license still will not refresh
      • Sign in with the same Microsoft account that the Microsoft 365 subscription is linked to.
      • If the issue continues, remove conflicting Office license files and reinstall Office from the subscription account’s install page.

    If the workbook is currently open with unsaved changes, avoid closing it until a successful save to a new name or different location is completed, because some save failures can cause loss of the latest revision.

    Good day Louisa, 

    Just to gently clarify before we go any further, this is a user‑to‑user support forum. I don’t have the ability to access or investigate individual accounts because this is a user‑to‑user support forum. 

    The "Couldn't refresh licence" message means Excel cannot validate the Microsoft 365 licence linked to your work account. When this occurs, Excel enters reduced functionality mode, allowing you to open and print files but preventing you from editing or saving them. 

    Before making any changes, please sign in to Excel for the web with your work account and confirm whether you can open, edit and save the workbook there. Also, create a backup copy of any unsaved work before closing Excel to avoid data loss. 

    Step 1: I recommend starting with the steps provided in the AI Answer. Since you mentioned that you are the administrator of the subscription, I will also provide some additional steps to help verify your Microsoft 365 licence in addition to the Excel troubleshooting steps. 

    Step 2: Check if the workbook can be saved 

    Please try selecting Save instead of Save As in Excel desktop app. You can also save the workbook to a different location or drive to preserve your latest changes. 

    Step 3: Verify your Microsoft 365 licence 

    Since you manage the subscription, please verify that your licence is assigned correctly: 

    Sign in to Microsoft 365 admin center. 

    Go to Billing > Your products > Locate your subscription and confirm that it is active.

    Then, go to Users > Active users > Select your account and open Licenses and apps. 

    Confirm that a licence including the Microsoft 365 desktop applications is assigned. 

    Under Apps, ensure the Microsoft 365 or Office applications are enabled. 

    If the licence is already assigned, remove it, save the change, then assign it again and save once more. 

    Step 4: Sign out and reactivate Excel 

    Note: Please make sure the workbook can be saved or backed up before performing these steps. 

    Open Excel > Select Excel > Sign Out. 

    Close all Office applications. 

    Restart your Mac. 

    Open Excel and sign in with your licensed work account. 

    Allow activation to complete, then test saving the file again. 

    Step 5: Reset Office licence information 

    Close all Office applications. 

    Open Keychain Access from Spotlight Search. 

    Search for Office. 

    Remove the Office licence related entries. 

    Restart your Mac. 

    Open Excel and sign in again with your licensed work account. 

    This refreshes the stored activation information and allows Office to obtain a new licence during sign in. 

    I hope this information is helpful. If you have any questions or need further support, please don’t hesitate to reach out at any time. 

    Thank you for your patience and understanding.
