What if I don't see the options to Manage Add-ins or the Microsoft Store? The required JavaScript API version is 1.3, but 2016 and newer have it built-in.You will need your login credentials for Outlook to install the add-in. If you do not see the 'Manage Add-Ins' or 'Manage Apps' option (for Outlook 2013, Outlook 2016, and ) or the 'Store' (Outlook For Mac), check with your admin to grant you access. You’ll need to have an active Microsoft Outlook or Live account to use the Outlook add-in. The Outlook add-in creates bi-directional sync with Pipeline and your Outlook calendar and contacts. The Pipeline Outlook add-in is built for Outlook 2013, Outlook 2016,, and Office 365 with an email that is hosted on a Microsoft Exchange server.
