Microsoft in 2018 announced a new learning endeavor called Microsoft Learn. And, in doing so, the company also has to shut down its old method of learning to avoid confusion and duplication.
Microsoft Virtual Academy will begin the shutdown procedure on January 31, 2019, with full shutdown later in 2019. Microsoft recommends that anyone with unfinished MVA courses should identify those and finish them before the January 31, 2019 date. This is the cutoff date for completing courses.
Check your MVA Dashboard frequently for courses you have started that are retiring. To earn your certificates of completion, be sure to finish any courses by January 31, 2019.
