Effective March 1st, 2022, Microsoft will be making the following changes to the way they bill for their Microsoft 365 licenses:
License cancellations, removals or prorations will no longer be available after 72 hours of adding a license. These changes will only be available upon the renewal of the subscription term (either monthly or annually).
License upgrades will only be available for eligible upgrade paths (i.e. Microsoft 365 E3 to Microsoft 365 E5). For non-eligible upgrades, the billing commitment may still be in effect.
Your choice of month-to-month or annual billing commitments. Month-to-month commitments will be billed at an additional 20% per license per month.
