Sometimes, when we receive email messages in which attachments are blocked by the Outlook. To no surprise, one of the most common ways to spread viruses is through email attachments. That is why Outlook blocks specific email attachments, including .exe and database files, to name a few.
If you ever try to send these files as attachments either to an Outlook email id or to any exchange server/ web-client, then you might get the following warning message in Outlook:
If you try to send the attachments mentioned above from Outlook to specific web client such as Gmail, then you might receive the following error message in Outlook:
Since Outlook 2000 service release 1, all Outlook versions include a security feature that blocks suspicious attachments automatically. This security feature is no doubt a bliss as the blocked attachments might put your computer at risk for viruses and threats. But, sometimes, a genuine attachment from a trusted sender could also be marked as potentially unsafe. In that case, you must download that attachment. In this post, we are going to describe specific methods that can easily let you open and download these blocked attachments in Outlook.
There are several ways to access the blocked attachments. In this section, we will shed some light on some of the most promising methods.
Method #1: Use a File Share or FTP Website to Share Files
You can ask the sender to share the file as a link instead of as an attachment. File share websites such as Google Drive, WeTransfer, HighTail, TransferBigFiles, DropSend, Egnyte, Dropbox, MediaFire, and more. These file-sharing platforms allow the user to share even files big as 20 GB. If you would like to share even bigger files, then you might consider subscribing to their premium features.
Method #2: Use a File Compression Utility to Share Files
You can ask the sender to compress the blocked attachment and resend it to you. File compression utilities such as WinZip and WinRAR can be used to perform these compression tasks. Compression changes the file name extension to .zip or .rar, which are not blocked by Outlook.
Method #3: Rename the File
If you or the sender don’t have access to a third-party compression tool, then you can ask the sender to rename the files to an extension, which is not considered as a threat by Outlook. For example, you can ask the sender to rename .exe file to a .doc file extension.
Method #4: Ask Server Administrator to Change the Security Settings
If you are using Outlook on the Exchange server, then you might ask your administrator to change the security of your mailbox to accept blocked attachments.
Method #5: Change of Security Behavior
If you do not use Outlook with Exchange or Server administrator allows you to change the Outlook security behavior, then this method is for you. This method involves modifying the registry. Special care should be taken while modifying the registry; if done incorrectly, then it might result in some severe issues. It is recommended to back up the registry before making any changes in it. The steps to change security behavior are listed below:
Note: If the registry key exists, then you can skip Step 4.
