Outlook: Open blocked attachments - how it works

In this practical tip, we will tell you how to unlock and open blocked attachments in MS Office Outlook.

Open blocked attachments in Outlook

Note: This practical tip is based on Outlook 2013 under Windows 7.

1. Open the registry editor by typing "regedit" under "Start" and "Run".
2. Change to the key "HKEY_CURRENT_USER \ Software \ Microsoft \ Office \ 14.0 \ Outlook \ Security". The 14.0 represents the version number and can therefore differ depending on the system.
3. If this key does not exist, right-click on Outlook and then select "Key" under "New".
4. Right-click on "Security" and select "String" under "New". Name this "Level1Remove" and then open it.
5. Enter the file types (for example EXE) that should no longer be blocked. Separate multiple file types with a semicolon (;).
