How to Stop Outlook From Downloading Images Automatically

Emails with images are a nice thing to see in Outlook—as long as they're sent from legitimate sources. Newsletters that look like websites are not only more attractive but also easier to read than their plain-text counterparts. But these emails may contain unwanted content that may cause harm to your computer or may be too large for your computer to handle.

Protect your privacy and your computer with just a few simple steps.

For Outlook 2019, 2016, 2013, and 2010

To prevent images from downloading in Outlook 2019, 2016, 2013, and 2010:

Select File > Options.
In Outlook Options, select Trust Center.
Under Microsoft Outlook Trust Center, select Trust Center Settings.
In the Trust Center dialog box, select Automatic Download.
Select Don't download pictures automatically in HTML email or RSS items.
Optionally, select Permit downloads in email messages from senders and to recipients defined in the Safe Senders and Safe Recipients Lists used by the Junk Email filter.

The sender is not verified. If somebody uses an email address that is not their own and is on your Safe Senders List, images are downloaded automatically.
Optionally, select the Permit downloads from Web sites in this security zone: Trusted Zone check box.
Select OK to close the Trust Center dialog box.
Select OK to close the Outlook Options dialog box.

For Outlook for Mac 2016

The process is slightly different for Outlook for Mac:

Select Outlook > Preferences.
In the Email section, select Reading.
In the Security section, select Never. Or select In messages from my contacts to have Outlook for Mac download images in emails from senders whose addresses are in your address book.

Spoofing an email address is easy. A sender uses your email address (which is in your address book) in place of the sender's email address to fool Outlook for Mac into downloading a dangerous file.
Close the Reading preferences window.

For Outlook 2007 in Windows

If you use Outlook 2007, follow these steps to prevent Outlook from downloading images:

Select Don't download pictures automatically in HTML e-mail or RSS items.
Select OK.

For Outlook 2003 in Windows

Here's how to prevent images from downloading in Outlook 2003:

Select Tools > Options.
Go to Security.
Select Change Automatic Download Settings.
Select Don't download pictures or other content automatically in HTML e-mail.
Optionally, select Permit downloads in e-mail messages from senders and to recipients defined in the Safe Senders and Safe Recipients Lists used by the Junk E-mail filter.
Select Permit downloads from Web sites in this security zone: Trusted Zone.
Select OK twice.
