Charged three times (299 THB each) on the same day for Microsoft 365 Personal across Copilot, OneDrive, and Word via Apple

Because the purchases were made through Apple, each in-app purchase was billed and managed by Apple as a separate subscription purchase. Microsoft states that Microsoft 365 subscriptions bought through a mobile app on iPhone or iPad must be managed in Apple ID settings, and Microsoft cannot cancel, refund, or modify billing for those third-party purchases. That matches the three separate Apple-billed entries shown for Copilot, OneDrive, and Word.

To avoid keeping three active subscriptions:

1. Wait for Apple’s refund decisions on the two duplicate purchases already submitted.
2. In Apple subscription management, confirm that only one Microsoft 365 Personal subscription remains active.
3. Do not purchase Microsoft 365 again from another Microsoft app while the remaining subscription is active.

To keep Microsoft 365 benefits across Word, OneDrive, and Copilot under the single remaining subscription:

1. Sign in to each Microsoft app with the same Microsoft account used when the subscription was purchased.
2. If an app does not recognize the subscription, sign out of that app and sign back in with the Microsoft account believed to have been used at purchase time.
3. If needed, use the app’s restore purchase flow. Microsoft Support specifically points to the restore-purchase steps for Office for Mac when an app cannot associate the App Store purchase.

Important effects of cancelling duplicate subscriptions:

• For Apple-purchased subscriptions, refund and cancellation must be handled by Apple, not Microsoft.
• If the remaining subscription is Microsoft 365 Personal, the Microsoft account should retain Microsoft 365 benefits on supported apps as long as those apps are signed in with the same Microsoft account associated with the purchase.
• If a Microsoft 365 Personal subscription is cancelled and not replaced, storage reverts to 5 GB of cloud storage, including OneDrive and Outlook.com attachments, plus 15 GB of Outlook.com storage. To avoid storage impact, make sure one subscription stays active.

If any app still shows no premium benefits after Apple leaves one subscription active, contact Microsoft Support after confirming the correct Microsoft account is signed in.
