To fix the issue of Outlook not showing images or graphics in emails, the following should be done:

1. Check Outlook’s email settings (Options > Trust Center > Automatic Download), and verify that the Show Images option is checked.


2. Clear image content from the cache. (File > Options > Mail > under Mail > Deleted completely the following items from your mailbox after > Clear Image)


3. Try disabling email security for images (Options > Trust Center > Trust Center Settings > Automatic Download > turn of both the Don’t download pictures automatically in HTML emails and Don’t download pictures in email messages automatically).


4. Make sure Outlook is connected to the internet. If working on corporate PCs, check that the corporate proxy settings are correctly configured.


5. Check the add-ins for Outlook, as the use of add-ins could block the email images.


6. Is your antivirus scanner or email security software blocking the images? Check your settings there.
