Go to your Microsoft account services
Navigate to https://account.microsoft.com/services/microsoft365 and sign in with the Microsoft account used to purchase your Microsoft 365 subscription.
Locate your Microsoft 365 subscription
Find your Microsoft 365 Personal, Family, or other plan in the list of active subscriptions and click the 'Manage' button beneath it.
Click 'Cancel subscription'
On the subscription management page, select 'Cancel subscription' (on some accounts this button reads 'Upgrade or Cancel'). If you only see 'Turn on recurring billing', your subscription is already set to expire and no further action is needed.
Review the retention page
Microsoft displays a 'Please review' page showing alternative cheaper subscription options before allowing you to proceed. Read through this page — it is designed to discourage cancellation by presenting discounted plan alternatives.
Select 'I don't want my subscription'
At the bottom of the retention page, choose between 'I want to keep my benefits' (keeps subscription) or 'I don't want my subscription' (proceeds with cancellation). Select 'I don't want my subscription' to continue.
Complete the cancellation survey
Microsoft asks for a brief reason for cancellation. Select the most applicable reason from the dropdown and optionally add feedback, then click 'Cancel subscription' or 'Confirm' to finalize.
Check your confirmation email
You will receive a confirmation email from Microsoft. Your subscription remains active until the end of the current billing period — you are not cut off immediately.
