Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
As many other people have demonstrated their annoyance at this here, I've just had the same message and had to go through to switch to a "classic" plan which is utter tripe. Microsoft clearly hoping to clean up on a massive monthly price hike from unexpecting people who believe that there's no other option. What a really horrible underhand sales tactic Microsoft. Do better.
It should have been offered as an option to upgrade not given as a price increase message, and you know it. Really poor effort and bad taste left afterwards. If I didn't need it, I would walk away from you given these shady tactics.
