Dear Mikey,
Good day! Thank you for posting to Microsoft Community. We are happy to assist you.
Based on your description, you're experiencing issues with Outlook 365 not showing embedded images. To better understand and investigate your issue, I may need some more detailed information from your side so that I can narrow down the issue in right way and also there are some troubleshooting steps that you can try:
- Are you using Microsoft365 business account or personal account (whichis ended with outlook.com or hotmail.com)?
- Are you using Outlook desktop client or Outlook web?
- If you are using Outlook desktop client, please check if the images are blocked: In Outlook, go to File > Options > Trust Center > Trust Center Settings > Automatic Download. Make sure that the "Don't download pictures automatically in HTML e-mail messages or RSS items" option is unchecked.

- Check if the email is in plain text format: If the email is in plain text format, images will not be displayed. You can change the format of the email by going to the Format Text tab and selecting HTML or Rich Text.
- Check if the sender is trusted: If the sender is not in your trusted senders list, images may be blocked. You can add the sender to your trusted senders list by right-clicking on the email and selecting Junk > Never Block Sender.
- If you are using Outlook Web, and issue is only with web version, would you please change another browser and have a try?
Please let me know when you get the information or tried the troubleshooting steps, I would continues to assist you.
