Why can't I open attachments in Hotmail?

Home » EMail » EMail Providers » MSN Hotmail

Summary: Opening attachments in Hotmail is easy - if Hotmail lets you. If Hotmail doesn't support the attachment type, Hotmail won't open the attachment. Period.

I am unable to open my Hotmail attachments. I am able to open attachments on other email services such as Yahoo, but not Hotmail. Why? (I hope your answer doesn't require me to open an attachment!)

Nope, no attachment's required.

The "why" is easy. Hotmail is attempting to protect you.

What to do about it, is less obvious, and a lot more cumbersome.

As we all know by now, viruses and other forms of malware are frequently transmitted by email in the form of attachments.

The problem is that no matter how many times people are told "don't open attachments from untrusted sources" they do so anyway. Or they trust sources that they shouldn't.

It's what some people call the Dancing Bunnies problem; send people an email that promises them dancing bunnies if they open the attachment, and darn it, a bunch of them are going to open that attachment no matter where it came from.

"Note the magical word permanently - you can't open that attachment in Hotmail. Period."

So, Hotmail "solves" this problem by disallowing many types of attachments. If you get an email with attachments that Hotmail does not support, you get this message:

Hotmail has permanently blocked the following potentially unsafe attachment(s)

Note the magical word permanently - you can't open that attachment in Hotmail. Period.

And if you follow through and click on the "More Info..." link next to that warning message, Hotmail's online help is quite explicit:

Hotmail doesn't support all file types. If you send an attachment that Hotmail doesn't support, the e-mail recipient wont be able to download or open the attachment.

I'm assuming that "send" should be "receive" because you most definitely can send attachments from a Hotmail account, no matter what type, as we'll see in a second.

There are two solutions, neither of them pretty:

  1. Have the sender send the attachment again, with a different name, or as a compressed file. ".zip" files are fine. ".exe" files are not. So if your sender creates a .zip archive of the .exe file that he's trying to send you, that you can save, and then decompress back into it's original form and name.

    Heck, just renaming the file is enough. Have the sender rename the .exe file into a .txt file and send that as an attachment. You'll be able to download it, and then rename it back to a .exe.

  2. Forward the attachment to a non-Hotmail account. Hotmail doesn't mention this approach, but sure enough, even though you can't open the unsupported attachments, you can forward them to a different account on a different service. If that service allows you to open the attachment, you've got it.

Hotmail's goal here is, obviously, to make it difficult to open malware in attachments by accident. You have to take steps of some sort; you have to think about it.

If you go through those steps, and you still get infected? Well, it was your own doing.

There seems to be a new problem here, related more to Hotmail's virus software than anything else. It seems the current virus software update has screwed up the ability to scan .zip files, and the virus scan doesn't know how to even read them. It just pops up an error saying "File contains too many embedded zip files" and won't let you touch it. You can't forward it, can't download it, and it just sits. They've changed things enough that you can no longer forward attachments that the virus scan hasn't already given the okay on. I've gotten this on several occasions now, all very frustrating, and forcing me to use another email service just for attachments.

I've sent a complaint to MS about it, hopefully someone will fix it quick. It only started happening in the past couple of weeks or so I think.

In a related issue, I can't type in any message into outgoing Hotmail e-mails. If I try to forward a message, thast message won't go either. I send an e-mail, but the content is lost. How come? What can i do about it?

Your solutions were useless to me because I only wanted to open my emails not attachements.

I contacted Norton live chat because I couldn't open email attachments in Hotmail. Their advice was as follows: IE/Tools/Options/Programs/Manage Add-ons/disable Norton Confidential. Open Norton and go to Phishing Protection and click ignore. BINGO everything works. Hope this helps someone.

I receive e mails with a photo attachment. When I open the e mail, the picture is a "gray block'". t is not with all e mails. I can open most of the pictures. Is there a way I can reprogram HotMail to open all photos? thank you

So, is hotmail now acting as big brother, deciding what I can and cannot open in my hotmail? I cannot send myself pictures from my own cell phone, even though it is on my "safe" list? Thank you hotmail, you have forced me to set up another email account under another provider. I will not use hotmail again. This is BS. How dare YOU decide what I can and cannot open.

I am able to open Hotmail attachments with Firefox that do not open with IE6, so I keep both browsers on my deskttop.I also notice that if I do not select the printer (even though I am not printing)to which my laptop is connected at the time, an attachment will not always open.
