Teams and Office Installer
As at the date of my publishing this post Content Manage 10.1 is still to be released but those in the beta program will have access to a preview in the near future. To assist in installing the zero footprint Office and Teams integrations there is a powershell script to create the Azure AD app and the related Office365 manifests. In the video below I demonstrate using this script.
Azure CLI is a pre-requisite for using this script.
To use the Microsoft APIs to retrieve either channel posts or group chats you need special permission from Microsoft, this may be request using their request form. You will need to supply the ID of the Azure AD app created for the Teams Integration as well as the reason you need organisation wide access to posts, probably for compliance purposes.
