In classic Outlook for Windows, select Download Pictures in the message’s information bar if you trust the sender and expected the content. Outlook blocks automatic internet image downloads by default, partly to reduce tracking through remote images.
01Confirm that this is classic Outlook
Section linkThese menu paths apply to classic Outlook for Windows, not new Outlook, the web app or the phone apps. Open a received message and look for the information bar explaining that pictures were blocked. This is a remote-content permission issue; it is not evidence that the image attachment or your mailbox has been deleted.
02Allow pictures for this message
Section linkFor a message from a trusted source, choose Download Pictures in the information bar above the message. In the Reading Pane, Outlook saves this choice automatically. If you opened the message in its own window and want pictures to remain visible next time, save the message after allowing the download.
03Choose how broadly to allow future downloads
Section linkTo allow a known sender or domain, right-click a blocked item in an open message and choose Add Sender to Safe Senders List or Add the Domain to Safe Senders List. A domain-wide choice is broader than trusting one address. Only add an entry when that scope matches what you intend to trust.
04Keep global changes deliberate
Section linkThe wider control is under File > Options > Trust Center > Trust Center Settings > Automatic Download. Review its options before allowing all downloads. Microsoft explains that remote images can act as tracking beacons, so leave unknown messages blocked when you do not need their images. Enabling all external content in other Office applications is not the Outlook-specific fix.
