Outlook blocks all Amazon S3 public images URL

New Contributor

When I add the image URL from the Amazon S3 bucket in the html email and send it out from our email server, the html email will be marked as junk email because the Amazon S3 image URL. This is the example what I added in the html email: 

<img style="height: 60px; width: 200px;" alt="" src="https://s3.us-east-2.amazonaws.com/tickitin/event-img/20168/d696cef742144426844e0647e89701ac.jpg" />

I tried to update the src in the <img> to other URLs like this one: https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png

The html email won't be blocked and was sent into inbox. I tried other public images online of Amazon S3 bucket and found all these images with the prefix URL https://s3.us-east-2.amazonaws.com will be blocked. Please help look into this. Thanks.

Just do not use these URLs. Could you export these images to other (your own) web site?
Yes, we can move those images to other servers but all of our images are stored in Amazon S3 bucket and Outlook is the only mailbox which blocks these images. Eventually we still need to use the URL of the images in Amazon S3 bucket.
