Suspicious emails?

Is it possible to read an email by just using the mouse pointer on it, in a way without opening it? Thinking about suspicious emails.

Is there possibly a setting, browser, program, mail provider or other things that make it possible?


Can it do any harm to use the mouse pointer over image links, attachments etc. in suspicious emails to get more information about them?

Will the sender then be able to access any information?

Do you have to physically click on images, links, attachments etc. with the mouse for the sender to get some information?

It doesn't matter if you click on them. Mail, Outlook and eM Client (and probably all email clients), don't download any images in an email unless you tell it to.


Why is that important? When your email client downloads any images meant to be viewed in the email, it has to request the image from the server where the image(s) reside. That server then logs the information of the user who retrieved the email. Why do they care? That tells them it's a live address and means you'll get even more spam, and your address will be added to any number of validated lists spammers sell to each other.


That's why Outlook and eM Client don't download any images until you tell them to. Apple's newer version of Mail takes a different approach. Rather than not downloading images like it used to, it now does, but then prevents the information of who retrieved from going back to the server.


So, short version. Click away. Just opening the email doesn't do anything nefarious. You'd have to actively do something you shouldn't for anything to happen. Like opening an attachment, following a link, or calling an unknown telephone number.

In computer parlance, when you have multiple choices and only one can be active at a time, they're called radio buttons. It's a direct reference to the radios in old vehicles where pushing one of several buttons would change the channel.


So, for this settings screen, these are your three radio button choices under the Security heading. Just as in a old car radio, you can only select one at a time. Clicking any other button turns the previous choice off.



You would want to use choice two or three. Never use the top choice.


For what version of Outlook, you should always have the latest version to keep up on bug fixes and security updates.


The most recent update for the free version of Outlook forced the ad "feature" back on. What look like emails in your Inbox are actually just ads, and will jump you to a website in your browser if you click on it. For quite a while, you could prevent those from showing by just removing/hiding the Other mail box. MS, um, fixed that so the ads always show.


That was the end of Outlook for me. I'm not paying $100 a year just to get an ad free version of Outlook. I went back to the free, open source eM Client. Looks and behaves almost exactly like Outlook.

Exactly where do i find this setting so i can se if it is set right?

The free version is in the App Store and is almost identical in appearance to the paid version. They will have the same version number per each update they receive. Version at this time of writing is 16.76.1 . You can always download the latest full version (and older paid releases) directly from MS here.


App Store version:



I wasn't going to install this thing again, but will in order to answer your questions without guessing.

Is it the free web version or the app version that is recommended?

I can't decide that for you, but the full version has more features. I didn't need them for mostly simple send/receive needs.

Exactly how do you remove what looks like emails in your Inbox that are actually just ads?

They are plainly noted as being an ad (icon at the right). You delete them a bit differently than regular emails. You can't click on the ad, then the trash icon on the toolbar since clicking on the "email" will simply cause it to open the ad in your browser. Instead, you hover your mouse over the ad so the trash icon appears next to the Ad icon. Click that to remove the ad without causing it to open.

Well, there's another change they just recently made. The default now is it's alway on to never download images. There's no longer an option in the settings to decide how you want it to behave.


For any email that includes embedded images, you now have to okay them one at a time. Or at least, that's how the free version works. Click on an email in your Inbox list. Where the body then displays, you'll see this at the top:



Click Download external images to retrieve them. Go to Settings does nothing useful. There are no choices to define:


But again, this is the free version. The options in the paid version of Outlook may be different.

But can these ads be a security threat if clicked on? Is it advised to hover your mouse over the ad so the trash icon appears next to the Ad icon - and click that to remove the ad without causing it to open every time they appear?

Yes that is how it appear on the iMac, but also using a Microsoft PC with Outlook, and i see pictures that are sent to me without downloading them in a small butt full version up to the left in the mail.

Should it not be like this, and is it a setting that i can and should do to avoid it?

When you move the mouse pointer over the image, an arrow appears, and you then get the message more actions. To bring up more actions, you have to click the mouse. You then get the options previews: save in OneDrive and download.

What exactly does one have to do here for it to constitute a security threat?

Microsoft themselves push these ads. You wouldn't think a company that big would need to resort to such nonsense for additional revenue, but there it is.


Other than that, you would certainly hope Microsoft wouldn't be so stupid as to accept and push ads that have a criminal element. But as John Galt said, clicking a link in an ad does nothing more than open a web site. That's it. There's still nothing that can happen unless the user chooses to do something dumb. Like filling in personal information merely because the site asks for it.

Is it advised to hover your mouse over the ad so the trash icon appears next to the Ad icon - and click that to remove the ad without causing it to open every time they appear?

That's the only way to delete an ad in the free version of Outlook without causing it to load the website linked to it.

Yes that is how it appear on the iMac, but also using a Microsoft PC with Outlook, and I see pictures that are sent to me without downloading them in a small but full version up to the left in the mail. …

No idea. I don't use the Windows version and can't verify, or even describe how it behaves.

I am using Outlook web version, and there I see pictures that are sent to me without downloading them in a small but full version at the top left of the email.

What do I have to do here for it to constitute a security threat in suspicious emails with attachments and/or images?


How can i set things so the images don't load, and should it be done for security reasons?
