<\/p>\n

Because of security settings in some versions of Microsoft Office, the following error may occur when opening documents downloaded from Internet, including Microsoft Outlook email attachments:<\/p>\n

\"office_protected_01_en\"<\/p>\n

or, alternatively, you could display the following alert asking you to enable editing feature for the document, since it comes from an untrusted source:<\/p>\n

\"office_protected_02_en\"<\/a><\/p>\n

In these cases, you can proceed with the following single-file solution<\/strong>:<\/p>\n

    \n
  1. save the file to your PC (for example in the Desktop folder)<\/li>\n
  2. click with the right mouse button on the file and select “Properties”<\/li>\n
  3. click\u00a0on “Unblock<\/strong>“<\/li>\n
  4. open the file from the corresponding Office program (Word, Excel, etc…) or by double clicking the file itself<\/li>\n<\/ol>\n

    \"office_protected_03_en\"<\/p>\n

    Alternatively, you can resort to a global\u00a0solution<\/strong>, a bit more risky, which consists in disabling some Office programs’ security settings<\/strong>. In this case, note that you are strongly encouraged to use other software (eg. antivirus) to be sure not to open malicious files. The procedure is the following, exemplified for Excel but to be repeated\u00a0for the other programs in the suite (Word, etc…):<\/p>\n

      \n
    1. Open Office program\u00a0(eg. Excel)<\/li>\n
    2. Click on\u00a0File->Options->Trust Center<\/strong> and then on “Trust Center Settings…<\/strong>“\"office_protected_04_en\"<\/a><\/li>\n
    3. Click on “Protected View<\/strong>”
      \n      \"office_protected_05_en\"<\/a><\/li>\n
    4. Uncheck the three checkboxes in the right side of the screen (or just a part of them if you want to reduce the chances of open unsafe files) and finally click OK<\/li>\n<\/ol>\n

      From now on all files, including Outlook attachments to be opened with the Office Suite (.doc, .xls, etc…), will be opened normally like all local files.<\/p>\n
