Microsoft Teams is being used as a most preferred method of communication platform by many organizations. By default in office 365 the group creation is enabled for end users which will allow them to create public and private groups. Few organizations are having the group creation disabled on the organization level for larger scale companies and have users request for creating the teams using a request form which will run through a automation process in the background with help of azure automation accounts ,Microsoft flow or few other mechanisms.
