Microsoft 365 Family users face 66% storage drop under new 2TB shared pool

Microsoft is restructuring cloud storage allocations for several Microsoft 365 consumer plans, replacing individual user quotas with a shared pool. According to Tom’s Hardware, the Microsoft 365 Family, Premium and Pro plans will move from 1TB per user to a combined 2TB limit for all users on the account. This policy change takes effect on renewals after 2 May 2027, meaning current subscribers retain their existing limits until their next billing cycle unless they manually change plans before that date.

How much storage do users lose?

The impact depends heavily on the number of users on the shared account. For a Microsoft 365 Family plan, which supports up to six users, the total available cloud storage falls from 6TB to 2TB. Tom’s Hardware calculates this as a 66.6% reduction in total capacity for households fully utilising the user slots. While Microsoft states that unused storage can now benefit the entire group, households with multiple heavy users will find their collective quota significantly tighter than before.

Why is Microsoft making this change?

Microsoft says the new model ensures storage goes where it is needed most and reduces the likelihood of individual users hitting personal limits. The company also notes that any additional storage purchased by the main subscriber will now benefit everyone on the account. However, industry reports suggest broader market pressures are at play. Tom’s Hardware links the move to a global shortage of storage hardware, noting that hard drive prices surged by 46% between September 2025 and January 2026, while enterprise SSD supplies remain constrained.

Who benefits and who pays more?

The change advantages households with a single power user and several light users, as the heavy user can now draw from the entire 2TB pool. Conversely, families with multiple moderate users may face higher costs. Tom’s Hardware points out that if four users each need 500GB, the shared 2TB cap is insufficient, forcing the subscriber to buy extra capacity. Additional storage starts at $1.99 per month for 200GB, adding a recurring cost that did not exist under the previous per-user allocation model.

What should IT managers do now?

Security and IT teams managing consumer or small business Microsoft 365 accounts should audit current storage usage across all user profiles. Identify accounts where the sum of individual usage exceeds 2TB, as these will be affected by the new cap. Review renewal dates to determine if the 2 May 2027 deadline applies to your specific subscription. Consider whether upgrading to a different plan or purchasing add-on storage now is more cost-effective than absorbing future overage fees or migrating data to alternative storage solutions.

What to do and how to stay safe: Microsoft 365

• Audit current storage consumption for all users on shared Microsoft 365 Family, Premium or Pro accounts.
• Identify users whose combined usage exceeds 2TB to anticipate future capacity constraints.
• Check subscription renewal dates to see if the May 2027 policy change applies to your cycle.
• Evaluate the cost of add-on storage versus plan upgrades for high-usage accounts.
