    Try this order in Excel and Windows:

    1. Close the workbook and Excel.
    2. In File Explorer, right-click the workbook > Properties.
    3. On the General tab, if Unblock appears, select it, then Apply and OK.
    4. Move the file to a folder that is used only for trusted files.
    5. In Excel, go to File > Options > Trust Center > Trust Center Settings > Trusted Locations.
    6. Check that trusted locations are allowed, then select Add new location and add the folder from step 4.
    7. Reopen the workbook from that trusted folder.

    If the workbook opens but shows a security warning, select Enable Content and confirm the document as trusted.

    If it still does not open, check macro settings:

    1. In Excel, go to File > Options > Trust Center > Trust Center Settings > Macro Settings.
    2. Use Disable all macros with notification so Excel can show the prompt to enable macros.
    3. If the file uses Excel 4.0 macros, also select Enable Excel 4.0 macros when VBA macros are enabled.

    Important: Enable all macros is not recommended because it can allow dangerous code to run.

    If none of that works, the most likely cause is an organizational policy blocking Trust Center changes or blocking that content type. In that case, the required action is to contact the organization’s IT administrator.

    Hello Glenn Mendoza,

    I understand this is time-sensitive. Could you please share the exact Excel error message or a screenshot with any personal information removed?

    Also, please confirm:

    • Does the workbook open with macros blocked, or not open at all?
    • Is the file from email, a downloaded ZIP, OneDrive, SharePoint, or a network folder?
    • What is the file extension, such as .xlsm or .xlsx?
    • Is this a personal PC or one managed by an organization?

    These details matter because unblocking the file may not work when a network location is treated as untrusted or when an organization’s policy controls macros. I would avoid enabling all macros globally because that would weaken Excel’s security.
