Microsoft's new program for Education and Non-Profits is called Elevate

Malawi seems to be handled via Microsoft's Morocco office. Whether there is a education lead at that office is something you might need to explore, or the education lead for Africa might be based elsewhere.
If you do not want to deal with the Microsoft piece yourself, you might want to partner with Techsoup Malawi which is a global Microsoft education / non profit partner.

As the Elevate program is still new, and with the tight staffing situation with Microsoft nowadays, you may find information about the education and non-profit outdated or not yet updated to Elevate program, or conflicting.
Do note that the A1 plan has a number of restrictions, like limited total storage for the school, and Microsoft prefers schools to go onto paid (but highly discounted) plans. Also the for education products are quite feature rich and a school using the plan may expect their partner to also be able to provide support and enablement on some of its features beyond email.
