CodeTwo Attach Unblocker allows fast and convenient configuration of Microsoft Outlook to unblock attachments blocked by Outlook by default (for example, .exe, .url, .reg files). The program is setup directly in Microsoft Outlook, which ensures quick and convenient editing.

From Microsoft Office 2000 with Service Pack 2 version (E-mail Security Update) onwards, Outlook has not allowed opening some attachment types due to safety reasons. These attachments are considered to be potentially dangerous as they may contain viruses or can damage the system. A dangerous attachment can neither be opened, nor saved on the hard disk. It will also be deleted while attempting to forward the message. Therefore, it is not possible to read such an attachment in Outlook. CodeTwo Attach Unblocker will enable you to read all previously blocked attachments.

In order to define the attachment types that should not be blocked, in Outlook 2007 and older versions, click on the Attach Unblocker button that is placed in the main toolbar. If you use Outlook 2010 click on the same button on the ribbon. In the textfield, enter the file extension (the attachment type) you wish to unblock and click Add. The file extension will be added to the Unblocked attachments list and after restarting Outlook attachments of that type will no longer be blocked and you will be able to save them on your hard drive.

More than one type of attachment can be entered in one edit field by separating the types with a semicolon. The types are not case sensitive.

The latest version of CodeTwo Attach Unblocker has one installation file that automatically checks bit version of your Outlook and installs accordingly to it. The improved program with a brand new User Interface is now available on CodeTwo's website – www.codetwo.com/freeware.
