This might be fine and dandy for K-12, but this is a huge ordeal for higher ed where the scale of our user base and usage is wildly different.
I ran the numbers, and our university's *active* accounts are about 92 TB over our calculated future pooled storage quota. That's active, used data for business, research, and students. There's a few heavy users, sure, but they are the vast minority. The ratio of FTEs to students skews the math badly, and this will force higher ed institutions to begin evaluating extreme user quotas (which will drive adoption/usage downward), or spend a lot of money uplifting from A3 to A5, or buying 10 TB storage packs as mentioned in the FAQ. Universities are often running on shoestring budgets, so this puts many in a severe bind. Even if we were to purge/delete the entirety of our high-capacity users in Exchange/SharePoint Online, our average active usage would still put us over the limit.
I understand not wanting to keep parked data around forever and not being able to provide effectively unlimited storage... But the storage pools described are simply insufficient for business, research, and student operations of a university. Our organization is not happy, and it feels like we're getting priced out of critical email/file/collab platforms.
