Viva Learning was launched to GA (General Availability) at Ignite 2021 Fall Edition and rolled out to commercial Microsoft 365 tenants during the last months of 2021. Your employees will, by default, be able to begin using Viva Learning right away without any IT administrator action to enable it or configure it. Now is the time to get to grips with what is available to configure, and how you can use the built-in functionality to good effect.
