In Outlook for iOS, first go to settings and then tap on 'Add-ins.' There, tap on the + sign next to Trello to enable the Trello add-in. The add-in will then appear in the command bar ribbon at the top. Next to the Trello add-in in the search results, set the toggle to 'On' to install the add-in. Type in 'Trello' in the search bar at the top right. In Outlook on the web, instead click on the gear icon in the top right, and select 'Manage integrations.' In Outlook 2013 or 2016, click on 'Store' from the Home tab on the ribbon.
Instead we'd recommend using an alternative like the Trello for Gmail Add-on. For example, an address accessed through Outlook will not work with the Add-in. IMAP Users: Email addresses using IMAP through Outlook will not be able to use the add-in. With the Trello add-in for Outlook you can create cards with descriptions and due dates, without ever leaving Outlook.
