Microsoft adds external image blocking to Outlook for Android.

Microsoft added a "Block External Images" feature in Outlook for Android. This feature, once activated, will prevent images in emails sent by people, not in your contacts from downloading automatically. Microsoft says "Block external images setting will not block images that are embedded in the email as attachments, including most emails sent from friends and family."

While not a security threat, blocking images in emails protects users privacy as these emails can sometimes include references to images hosted on the internet and can be used to track whether someone has read an email. All in all, this blocking feature is a welcome addition if you value your privacy. 

By default, the image blocking setting is disabled. In order to activate, tap the hamburger menu - the three horizontal bars at the top left - then tap the settings icon at the bottom left. Tap your email account or any other email if you have several accounts and toggle the blocking setting. It turns blue when activated.

This update is already available to download in Google Play Store.
