Office 365 Centralized Deployment
EmailSentry uses a standard Windows Installer (.msi) installation. Download the version 2 installer here.
Most companies with experience pushing .msi files to their users should be able to install EmailSentry without their users having to do anything. They can use Group Policy to prevent users from uninstalling the Add-in, so users are forced to deal with "unsafe" email immediately.
Install Fixed Config File
EmailSentry requires a Fixed Configuration File stored on the user's PC at C:\ProgramData\SecurEmail LLC\EmailSentry.xml. The .msi creates this file with settings for the Free Trial. This file should be updated to a company's Full License settings (see Features, Configuration, and Customization) by copying your Fixed Configuration File to this location on each user's PC.
This copy can be done as part of the installation process.
Copy the file after you run EmailSentry.msi as part of your GPO or other push method.
Or you can have the .msi fetch your custom Fixed Configuration File from our servers by specifying your EmailSentry CompanyCode and CompanyPassword on the .msi command line, like this:
EmailSentry.msi CODE="YourCompanyCode" PASS="YourCompanyPassword"
You can silence some popups during the installation by installing the SecurEmail LLC publisher certificate into HKLM/HKCU Trusted Publisher Certificate Store. You can install this certificate from the command line with:
certmgr.exe -add SecurEmailLLC.cer -c -s -r localUser TrustedPublisher
Install Certificate Interactively
Now the Install will run without asking you to verify the publisher.
