How to prevent Outlook from blocking attachments with .exe extensions
I personally really like using Outlook 2013 as a desktop client for emailThanks to its great power and huge number of options, it's hard to miss something about web clients like Gmail when using it, and it also gives us the advantage of being well integrated with other Microsoft tools like OneNote. However, one problem it does have is that its security restrictions are sometimes a bit draconian.
For example, there is the case of attachments. Here we find that Outlook has a black list of file extensions that are blocked under the idea of ​​guaranteeing greater security.The problem is not so much that they are blocked by default, but rather that the option to unlock the files is not given if they come from a reliable source What can we to open such an attachment if necessary?"
As an official solution to this problem, Microsoft suggests us to share these types of files using FTP servers or cloud services like OneDrive, and send the link by email, or send them in a .zip or change the extension to the file. The problem with all these ideas is that they are actions that must be carried out by whoever sends the file If someone already sent us a file with a banned extension, and we must open it urgently , none of these solutions apply.
Luckily, there is a way to force Outlook to allow us to open those files. To do this we must close Outlook, go to the Windows registry and navigate to the following path:
HKEY_CURRENT_USER/Software/Microsoft/Office/XX.X/Outlook/Security
Where XX.X corresponds to the version we are using (Outlook 2013 is 15.0, 2010 is 14.0, 2007 is 12.0 and Outlook 2003 is 11.0). Once there, we must create a new string value with the name Level1Remove.
Then we must open the entry that we have just created, and in the value information field > write each of the file extensions that we want to add as exceptions to the blocking, separating them by semicolon. For example, if we want Outlook to allow us to open attachments ending in .exe, .gadget and .msi, we must write the following:"
.exe;.gadget;.msi
To perform this step it may be useful to consult the official list of blocked extensions. When we're done, we just save the changes to the registry, start Outlook again, and you should be able to open the attachment we added as an exception.
