Installing the Hummingbird Plugin

iOFFICE allows you to add the Hummingbird app directly to your Outlook Calendar using a Hummingbird plugin. Use the following procedures to make the Hummingbird app plugin available in Outlook. The first procedure details the installation for the Outlook Web App (OWA) and the second for the Outlook desktop client. If you have access to both versions of Outlook, installing it in one place will result in the add-in being available in both places. 

IMPORTANT! - Prior to using the following procedures, you should access Admin → Marketplace → Hummingbird for Outlook in your iOFFICE site and download the manifest file (XML file) that will be needed to successfully install the add-in.  Call 713-526-1029 or send an email to if you have any questions.
