Installing the OWA plugin doesn't go as expected based on the shipping documentation.


Follow these steps for proper installation.

The plugin must be installed onto your Exchange server. 

Download the Retain install package to your Exchange server and extract it. Don't worry you are not going to install Retain here, just one bit of it.

  • The installer will ask you to choose a file location for the plugin files. The default is C:\Program Files\Microsoft\Exchange Server\v15\ClientAccess\Owa\

  • Click Close when it is complete.

Server Side Setup

  • Select Organization from the left sidebar.
  • Select Apps from the pane top tab bar.
  • Click the down-arrow next to the add + icon, and select 'Add from file'.
  • Browse to the install location C:\Program Files\Microsoft\Exchange Server\v15\ClientAccess\Owa\Retain and select manifest.xml and Open.
  • Click Next to install to the server, this will make it available for the users to install to their OWAs. If you double click the plugin you can set it to enabled or mandatory for the client.

Client Side Setup
  • Log into the Outlook Web App (https://[yourserver]/owa) as a user.
  • Click the gear icon near the top right next to your users name and select Manage apps...
  • A list of apps available to the users will be listed. Notice that Retain App is available but disabled. Select the Retain app and in the right sidebar click the Enable link.
  • Navigate back to your inbox with the right arrow or by clicking on your username and choosing My Mail.
  • Browse to any message. Within the Viewer pane on the right or if you open the message in its own window, you will see a Retain link inside a grey bar.
  • Clicking the link will reveal a Retain logo image and clicking on that will open a new window in the Retain archive.
