How to cancel Microsoft 365 by mail

  1. Note your account details

    Check the account email, the plan or product name and the invoice or order number from your latest receipt before anything else. A request that does not match the account on file at Microsoft 365 is the easiest one to set aside.

  2. Write your request

    Postbye turns the request into a finished English letter headed “Subject: Subscription termination – Microsoft 365”: close the Microsoft 365 account, stop every charge and reply in writing.

  3. Mail the letter with a receipt

    Post it by certified mail to Microsoft 365 in Redmond, United States, using the exact address below, and note the tracking number.

  4. Keep the proof of delivery

    Delivery confirmation is your evidence that Microsoft 365 was asked. Watch the next statement or two for any further Microsoft 365 charge.

With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a software or app subscription

Software plans are billed per plan or per seat, often yearly, and the app store version is billed by the store rather than the developer, so the request has to name the plan and who bills it.

A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.

Microsoft 365 lets you cancel directly (online (Services & subscriptions)). A letter is the fallback that leaves a dated record when the direct route fails.
