Microsoft 365 is cancelled through your Microsoft account, not inside Word or Outlook. The main thing to watch is your OneDrive storage: it drops to 5 GB when the subscription ends, and anything over that needs to be moved.
Microsoft 365 subscriptions are managed centrally in your Microsoft account, alongside Xbox Game Pass and other services. Cancelling turns off recurring billing; it does not delete your account or immediately remove access.

Cancel Through an App Store
If you subscribed to Microsoft 365 through the Apple App Store or Google Play Store, Microsoft cannot cancel it for you. Cancel in the store where you subscribed:

The Storage Catch: OneDrive
The biggest practical issue when leaving Microsoft 365 is storage. Your OneDrive allowance drops from 1 TB to the free 5 GB when the subscription ends. If you are over 5 GB, Microsoft gives you a grace period - typically several months - during which you can view and download files, but you cannot add new files. After that, files may be deleted.
What Happens to Office Apps
Installed Office apps do not uninstall themselves when the subscription ends, but they drop into reduced functionality mode. You can still open and view documents, but editing and creating new documents requires an active subscription or a one-time Office purchase.
Refunds
Microsoft generally does not offer refunds for monthly subscriptions. For annual plans, you may be eligible for a prorated refund if you cancel shortly after renewal and have not used the service. Contact Microsoft Support to request one.
What Happens After You Cancel
You keep Microsoft 365 features until the end of the current billing period
OneDrive storage drops to 5 GB after that date
Office apps enter reduced functionality mode
Your Microsoft account, email, and purchased content remain active
Track Your Software Subscriptions
Microsoft 365 is often one of several software subscriptions - Adobe, Dropbox, Canva, cloud storage. A single list of every renewal date stops the annual ones from auto-charging before you review them.
Quick Unsubscribe takes you straight to the cancel page for each service in your list.
Adobe will let you cancel in a few clicks - and then charge you up to half of your remaining contract to do it. The fee is real, but it is avoidable if you know which plan you are on and when you are allowed to leave for free. There is also a second cost nobody warns you about: your cloud storage drops to 5 GB the moment you leave.
Cancelling Dropbox is straightforward, but the storage drop is the catch. When the subscription ends, your account reverts to the free 2 GB Dropbox Basic plan. Anything over that limit needs to be moved or deleted.
Forgotten subscriptions can drain hundreds of euros a year. Here is how to find every active subscription and cancel the ones you no longer want. The cancelling is the easy part - the work is tracking down charges that are spread across app stores, PayPal, your bank and the services themselves.
