Disable image attachment thumbnail previews.
Please disable image attachment thumbnail previews, or allow an option to disable it. Outlook takes significant time generating the thumbnails and does so each time the email is opened, or even just highlight with the reading pane open. while it is generating the thumbnail outlook freezes and becomes unresponsive. Also in some cases the thumbnail can contain personally identifiable or confidential information. This may be acceptable for the recipient to see in private, but should be exposed to any passerby on the email screen. So provide a feature to disable email attachment thumbnails as well as previews for security reasons.

Can you please allow us to only opt-in to the thumbnail preview that has just started appearing. We see no reason for the change and it is significantly slowing down our work. I cannot understand why this has been introduced with no notification, and no option to disable it.
Anyone over there care anymore? Anyone at all? https://www.zdnet.com/article/microsoft-releases-emergency-security-update-to-fix-two-bugs-in-windows-codecs/
Please allow to disable the image thumbnail previews VERY irritating...probably will go back to MacMail.
multiple UserVoice entries in regards to this. please allow to disable the image thumbnail previews (as in .tif, for example)!! Other attachment types do not always show a preview (or allow me to disable it).

To shrink photos on our work server, we select all and send the images "to mail recipient" with a smaller option (eg. medium). Delete the old photos, highlight all attachments in the email and drag back to the server.
Now that we have upgraded to the new Outlook, we can no longer "highlight all" attachments to drag back. We have to drag them 1 by 1 or hold "control" whilst clicking them all (which stops working after 5 or so selections and clears it all!).
Please have an option to re-activate the preview!!!! Why get rid of something that didn't need changing..

Not only does this cause additional load time for email, but in some cases the thumbnail can contain personally identifiable or confidential information. This may be acceptable for the recipient to see in private, but should be exposed to any passerby on the email screen.

I believe that these attachment thumbnails which have recently started to appear in the inbox of Outlook live are an extreme security risk.
I very nearly clicked on an attached pdf file thumbnail tonight and I believe that they can carry viruses. I try to be SO careful and Microsoft do this!. You are MUCH less likely to click on the traditional attachment within the email than these thumbnails which are attached to the subject line!
We are constantly informed how dangerous it can be to open an attached doc so I don't know what the thinking is? :(
I eventually managed to find out where to stop the attachment thumbnail showing....what a waste of time though and what a very poor and unnecessary idea.
Please give us the option to disable the picture thumbnails. When we receive a picture that have more than 5 mb, it takes a lot of time to open the email. Why you don't care?
Not such a dumb idea now huh? https://mspoweruser.com/thanks-to-a-new-vulnerability-a-single-file-can-comprise-your-android-device/
Whoever is in charge of your security there should be fired for really not caring about security. This is a legitimate security concern and a very obvious attack vector. There is no doubt someone trying to exploit this at this very moment, if they haven't already. More here:
Please give back the list view of attachments. Thumbnails are fine but first they take a lot of space, and second names are cut off.

It's far too easy to click on Preview instead of opening an attachment, which is both a nuisance and a waste of time.
I get a ton of attachments; I need to open them. I don't want to preview them--in fact, I never use the preview feature intentionally. I just don't care.
(Does the Preview feature have any security value? I am inclined to doubt it. To be honest, though, even if it did I don't think it actually buys me anything *because I still need to open the **** attachment* from certain senders.)
they appear as thumbnails, which is already annoying as it takes 90% of the screen, but on top clicking on "remove attachment" dies not remove it at all. extremely frustrating in a suite that is already pretty bad in terms of ergonomics and functionalities.

This is a nice but lets do it an optional characteristic, please.
Wastes time just trying to open a mail
James Morgan commented
This is a major problem for us affecting many users as we deal with high res tif drawings all the time. Clicking those mails can freeze the client for literally minutes at a time, it's rediculous.
Trevor Hookings commented
Yes totally agree. The file name is often cut short. There must be a file name only option for reading pane attachments. This has only been a problem with outlook 2016.
Jean-Marie Huys commented
All of the .tif attachments can be seen as thumbnails previews in Outlook Client 2016, this causing the e-mails containing them to open very slowly.
IT guy commented
Please do something with that. Nobody of my users like this feature.
I agree. This feature can create slowing reading mails.
