This only happens in Outlook Application
I have tried all the solution provided by Microsoft but none of it works.
- Modify BlockHTTPimages in registry (Don't have this in my registry)
- Changes Trust Center settings
- Change Internet Options (Do not save encrypted pages to disk)
My organization is using IMAP/ SMTP server but I don't think the issue is related to the server. This issue only occur to Outlook application, but in web, it works fine.
