Outlook likes to block images in emails by default. It's just one of the many issues with Outlook. You can usually fix this by adding the sender to your "Safe Senders" list by right clicking.

Microsoft's instructions for this can be found here. Talk to your Mail administrator for other options in regards to this matter.

Outlook 2007, 2010, and 2013 - Secure Images

Internet Explorer has a security setting that, when enabled, prevents Outlook from displaying images with a secure URL. (Image URLs starting with "http" will display, not URLs that start with "https".)

If Outlook 2007, 2010, or 2013 displays some - but not all - images, you may need to change the setting in your Internet Explorer web browser or desktop software.

To change the setting in Internet Explorer:

  1. Open Internet Explorer.
  2. Go to Tools > Internet Options.
  3. Click the Advanced tab.
  4. Scroll down to the Security settings list, then uncheck the "Do not save encrypted pages to disk" option.
  5. Click OK.

Before the changes take effect, it may sometimes be necessary to clear the cache in Internet Explorer and close Outlook (File > Exit to close fully). After relaunching Outlook, send yourself another email with an image that did not display previously.
