Image not displaying in Webmail EX3

Hello everyone,

Since yesterday, 18/05/2026, images no longer display in emails received on the EX3 server, for example via webmail.

Is this problem known and being addressed?

Thank you,

Hello,

Are these the images embedded in received emails, or the images that the webmail has to fetch from your correspondent's server, or the images that are part of the webmail's own decoration?

In the second case, it's a configurable option, because there is a privacy concern. By fetching an image from its server to display it, your sender can infer that you are reading their email. By default we will assume that you do not want to let this information leak.

Hello,

These are the images included in the received emails. They were displaying fine before 18/05. I also have the issue on EX3 and EX4.

When a received email is forwarded, the image displays correctly in the forwarded message. It therefore appears to be a bug related to the display of images received via webmail.

I hope I have been clearer to help you better understand this problem on your side.

Thank you.

See your options in Outlook. That's definitely where you can choose to display them or not.

Same for webmail.

Hello,
Same issue on EX2.
I checked the settings but found nothing.
Did you find a solution?

Can you take a screenshot that shows the problem?

Hello,

Here is a screenshot; you can see that the image in the email (accessed via webmail) is not displayed (blank) within the text content.

Have a good day,

Hello,
I confirm we have exactly the same problem on ex4 since May 18.
It is indeed the images that are embedded directly in the emails that are not displaying.
For your information, there is no cross or outlined area indicating that the image isn’t displayed; there is simply nothing.
And the only way to retrieve the image is to forward this email, and then the image appears.
So the image does exist somewhere.

Hello, we have the same issue.

Has anyone found an explanation?

Exactly the same problem here since 18/05, has anyone found a solution?

I just found this incident report, could it be related?

Same problem for us with Outlook Web accounts on EX5.
Only IMAP email clients load the images and correctly display HTML‑formatted emails that contain images.
It's handy when you receive a snapshot of a client in the body of the email ...

Well, the fix apparently still hasn't been provided by Microsoft...
Since May 18, it's dragging on.

Thank you for the feedback; it’s concerning for a return to normal, as it only mentions Outlook Classic while it also affects reading emails in the OWA web browser.

Hello,

Relieved to see that this problem is widespread but has been ongoing for 10 days.

Is there a solution?

Thank you in advance

I think we’re soon approaching a record in terms of the time it takes to resolve a problem…

Outlook...

Big problems with Outlook New and Classic as well.
Exchange, Microsoft and Windows user accounts interfere with each other and cause connection issues, and this happens on 2 out of 8 workstations; the messages aren’t all downloaded, even with an Exchange connection on Outlook Classic, which by the way is about to disappear natively on Windows 11.
The only solution so far has been to use Thunderbird.
Huge regrets for having chosen the OVH/Exchange plan...

I feel that Microsoft is doing everything to shut down Exchange installations that are not hosted in its M365 cloud. It starts with a few registry keys to change in order to use “the new Outlook” which no longer has a version number, then creates very annoying malfunctions and drags on to fix these regressions (waiting for the next “Patch Tuesday” — which is actually today).

See the Microsoft article: https://support.microsoft.com/en-gb/office/images-are-not-displayed-in-emails-newsletters-or-signatures-in-classic-outlook-74600b12-905a-4f2c-9de5-ba295a675216

“For the channels that do not have the fixed build yet, we expect the fix to be released with the June 9th public updates.”

So yes, it’s easy to patch your Outlook, but when it comes to production servers (Outlook Web) where a reboot will likely be necessary, it can’t be done in a quarter of an hour.
