File Sharing Hacks

If you want to receive a file of a type that is blocked by Outlook, you can ask the sender to either make the file available without using Outlook, or make it less likely to be blocked by Outlook. The following are some safe ways to share files with people that you trust.

  • Use a shared server    You might want to ask the sender to save the attachment to a server or an FTP site that you can access. This can include a secure network share server such as SharePoint. The sender can send you a link to the attachment on the server or FTP site. You can click the link to access the file and save it to your computer.
  • Use a file compression utility    Using a compression utility, such as WinZip, creates a compressed archive file that has a different file name extension. Outlook doesn’t recognize these file name extensions as potential threats. Therefore, it doesn’t block the new attachment. Many third-party compression utilities are available.
  • Rename the file    You can request that the sender rename the attachment to use a file name extension that Outlook doesn’t recognize as a threat. For example, an executable file that has the file name extension .exe could be renamed as a Word file that has a .docx file name extension.

Ask the sender to resend the renamed attachment to you. To save the attachment and rename it to use the original file name extension, do the following:

  1. Locate the attachment in the email message.
  2. Right-click the attachment, and then click Copy.
  3. Right-click the desktop, and then click Paste.
  4. Right-click the pasted file, and then click Rename.
  5. Rename the file to use the original file name extension, such as .exe.
