- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Managing billing and subscription renewals for a base plan and an additional storage add-on.
- Observed behavior
- Seeking clarification on whether the expiry date of the Extra File Storage add-on needs to match the base Microsoft 365 Business subscription.
Ensure you have global or billing administrator privileges in the Microsoft 365 admin center so you can access the subscription details and billing cycles.
Maintain Base Subscription Continuity
The expiry dates do not strictly need to match, but the base subscription must remain active for the add-on to function.
Microsoft 365 Business plans act as the base subscription, while Office 365 Extra File Storage is categorized as an add-on. Because of this dependency, the two can have different billing cycles (e.g., one monthly and one annual), but the add-on cannot exist independently.
Ensure auto-renewal is turned on or manually renew your Microsoft 365 Business base plan before its expiration date. If this plan is disabled, the Extra File Storage add-on will be automatically disabled.
Navigate to the Microsoft 365 admin center > Billing > Your products to view whether your commitments are monthly or annual for both the base plan and the add-on.
Contact Your Reseller or Partner Center
If you purchased your subscriptions through a third-party reseller, you must manage alignment options directly with them.

Frequently Asked Questions
What happens to my Extra File Storage if my Microsoft 365 Business plan expires?
Because the Extra File Storage is an add-on, it is entirely dependent on your base Microsoft 365 Business subscription. If the base plan expires or is disabled, the storage add-on will be automatically disabled, and you may lose access to the additional space.
Can I manually align the billing dates of my Microsoft 365 base plan and add-ons?
If you purchase directly from Microsoft, aligning dates can sometimes be done by managing billing terms in the Microsoft 365 admin center, though pro-rating rules apply. If you purchase through a reseller, you must contact them to adjust your billing cycles so they align.
How do I check the current expiration dates for my Microsoft 365 subscriptions?
Sign in to the Microsoft 365 admin center as a global or billing admin. Go to the 'Billing' section and select 'Your products'. Here, you will see a list of all active base subscriptions and add-ons, along with their respective renewal and expiration dates.
