I currently have a grandfathered Microsoft 365 Family subscription with 1 TB of OneDrive storage per person and a renewal date of March 30, 2027. If I redeem one or two additional Microsoft 365 Family 12-month subscriptions today, will my account keep the 1 TB-per-person storage allocation through the prepaid term, or will it be converted to the new 2 TB shared-storage model before the prepaid term ends? Please provide the official policy for grandfathered subscribers.

Co-Pilot answered as follows:

If you stack 2 years now and your current expiration is around March 30, 2027, your subscription would likely be extended to approximately March 30, 2029.

The big unknown is whether Microsoft will grandfather the 1 TB-per-person entitlement through the entire prepaid term, or convert you to 2 TB shared on May 2, 2027 (or at some other migration point) even though you've already paid through 2029.

I have not found an official Microsoft statement that explicitly answers that exact scenario. The transition information I've seen discusses:

new subscriptions,
renewal dates,
and plan changes,

but does not clearly state what happens when a grandfathered subscriber prepays several years beyond the transition date.

I gather the following might help - https://techcommunity.microsoft.com/discussions/microsoft-365/regarding-the-update-on-the-one-drive-storage-in-microsoft-365-family/4563850

Microsoft has officially clarified that existing Microsoft 365 Family subscribers will remain on the legacy 1 TB per person model until their next renewal after 2-May-2027. Even if you redeem multiple years of prepaid Family subscriptions before that date, the shared-storage entitlement (2 TB pooled across the family) will only apply at the first renewal following the transition date but not earlier.
