Installing the outlook plug-in

 

Before Installation

Please make sure your Outlook Program is closed out prior to installation of the plug-in.

  1. From where you downloaded the installation file, double-click to start the installation.
  2. Click Run on the security warning if it pops up.
  3. Click Next  on the Proofpoint Encryption Plug-in for Microsoft Outlook Set-up screen.
  4. Check the box for the license agreement and click Next.
  5. Click Next to install in the default folder or click Change to select another location.
  6. Click Next.
  7. Click Install.
  8. Click Finish when the installation has completed.

Verify Plug-in Installation

  1. Launch Outlook.
  2. Compose a new message.
  3. Look for the Send Securely button in the message composition window.

In order for the plug-in to work properly, Outlook must have been installed from a local installation.  Cloud-based installs of Outlook have caused the plug-in to not work properly.
