If files suddenly cannot be saved in locations such as Documents, one likely cause is Windows Security Controlled Folder Access, which can block apps from writing to protected folders. A practical first check is:

  1. Open Settings.
  2. Go to Privacy & Security > Windows Security.
  3. Open Virus & threat protection.
  4. Open Ransomware protection.
  5. Check whether Controlled Folder Access is turned on.
  6. If it is on, turn it off temporarily and test saving again.

If saving works after that, the protection was likely blocking the app.

Other common causes from Office security settings:

  1. File is opening in Protected View
    • In the Office app, go to File > Options > Trust Center > Trust Center Settings > Protected View.
    • Review the Protected View options.
    • Files from the internet, email attachments, or potentially unsafe locations can open with restrictions.
  2. File or folder is marked read-only
    • In File Explorer, right-click the file.
    • Select Properties.
    • If Read-only is checked, clear it and select OK.
  3. Trust Center settings are managed by policy
    • If macro, Protected View, or other Trust Center settings cannot be changed, the setting may be controlled by an organization policy. In that case, the IT administrator must change it.
  4. Trusted Documents settings
    • In an Office desktop app, go to File > Options > Trust Center > Trust Center Settings > Trusted Documents.
    • Review whether trusted document behavior is affecting how files open.

If the exact message is “file not found” when saving to Documents, that can also indicate the app is trying to save to a location that no longer exists or is unavailable, rather than only a security block. In that case, try Save As and choose Documents again manually or save to Desktop first to confirm whether the issue is specific to that folder.

    Hello Ryk Kleynhans

    I can see that you wish to change the setting on your Microsoft sercurity.

    Since the Windows Security and Office Trust Center checks have already been covered, the next thing to verify is whether your Documents folder still points to a valid location.

    This commonly happens when Documents was redirected to OneDrive, but OneDrive was later unlinked, moved, signed into with another account, or its folder location changed.

    1. Open File Explorer and select Documents under This PC.
    2. Right-click an empty area inside the folder and select Properties, or right-click Documents in the navigation pane and select Properties.
    3. On the Location tab, check the path shown there.
    4. Confirm that this folder actually exists. For example, determine whether it points to a local path such as C:\Users\YourName\Documents or to a OneDrive path that is no longer available.
    5. If it points to an old or missing location, select Restore Default, then select Apply. Restart the computer and test saving again.

    If Documents points to OneDrive, also select the OneDrive cloud icon in the notification area and confirm that OneDrive is running, signed in to the intended account, and not displaying a sync or storage error.

    Please let me know:

    • Which application shows the error, such as Word, Excel, or another program
    • Whether Documents currently points to a local folder or OneDrive
    • The full error message, without any personal information
    • Whether this is a personal or organization-managed computer

    Feel free reply back to this post and update me on this issue, I'll be happy to help.
