Dealing with Blocked Attachments in Outlook
The first thing to recognize about the unsafe attachment system in Outlook is that the program will not allow users to do anything with the attachment. You can't save it, print it, open it or even delete it, making few options available for the recipient.
What you as a user do about the attachment problem may depend on (1) how well you know the sender, (2) how often you get attachments you can't open, (3) how well you know your Exchange administrator (if applicable), and (4) how willing you are to mess with your computer's registry. Let's go through the options and then you can choose.
1. Ask the sender to send the file in a compressed format.
If someone must send you an executable file or a script, ask them to zip it first. This will produce an attachment with the .zip, .rar, etc. extension that Outlook will allow you to save. If the sender does not know how to zip a file, see if you can get her to rename it with an underscore as the last character. For example, if they were sending virus.exe to you, ask them to rename it as virsu.ex_.
2. See if you can download the file from the sender's FTP site.
Users who are somewhat tech-savvy could ask the sender of a blocked attachment to allow you to download it from their FTP server. Of course, not everyone has access to an FTP server and some people might not even know what an FTP server is, so this may not always work.
Senders can always try to upload the attachment to file sharing services like Rapidshare or the now-defunct drop.io and send you the link in email. Again, this method represents a possibly significant technical hurdle, so it might not work out.
3. Chat with your Microsoft Exchange administrator
If your corporate email is managed on an Exchange Server, check with your IT department to see if they will agree to allow you tor receive files that are currently blocked. If you are on good terms with them, they might give you a break and change your account to allow the files through. Of course, this won't help if you are using Outlook with another type of email account such as POP.
