Cancel by reason

Moving / relocation

If you move to a country where the specific Microsoft 365 plan is not available, provide proof of new address such as a utility bill or tenancy agreement. Microsoft will review eligibility for termination or plan change. Applicable law: Consumer Contracts Regulations 2013 for online purchases when change of circumstances affects supply.

Price increase

If Microsoft increases the recurring price for your existing subscription, you have the right to cancel before the new price takes effect. Provide the renewal notice or billing statement showing the price change. Applicable law: Digital Markets, Competition and Consumers Act 2024 and CMA guidance on unfair auto-renewal.

Death of subscriber

Immediate family members should send a copy of the death certificate and proof of account relationship to Microsoft's support for account closure and data access instructions.

Legitimate grounds accepted by Microsoft

Microsoft accepts cancellation for non-delivery of services, significant changes to agreed features, or legal prohibitions. Provide supporting documents that show the issue e.g. service outage evidence or official notices. Applicable law: Consumer Rights Act 2015 (services must be performed with reasonable care and skill).

End of commitment

For plans with an annual commitment, the contract ends at the expiry date shown in your account unless you cancel before auto-renewal. Check Services & subscriptions for the expiry date and cancel before that date to prevent renewal.

Cooling-off period

For online purchases you have a 14-day cooling-off period under the Consumer Contracts Regulations 2013. If you started using downloadable or streaming digital content and gave express consent to immediate start, the digital content exception applies and you lose the right to a refund for that download or streaming after consent.

Negotiate or save

Before you cancel: attempt to negotiate

Contact Microsoft support via your account and ask for retention offers by explaining your reason to cancel. Research does not list standard retention discounts publicly; Microsoft sometimes presents refund eligibility or credit during the cancellation flow. If you want a lower price, ask explicitly for any available promotional or loyalty pricing during the support call or chat. Keep written confirmation of any new offer.

What cancelling saves you

Compute your yearly saving using current plan prices.

Example 1 - Microsoft 365 Personal: £7.08 per month or £84.99 per year. Annual cost: £84.99.

Example 2 - Microsoft 365 Family: £8.75 per month or £104.99 per year. Annual cost: £104.99.

If you cancel Microsoft 365 Family (£104.99 per year) and switch to Google Workspace Starter at £5.90 per user per month (annual commitment), the competitor yearly cost for one user is: 1 user x £5.90 x 12 = £70.80 per year.

Saving calculation switching Family to 1-user Google Workspace Starter: £104.99 - £70.80 = £34.19 saved per year.

If you cancel Microsoft 365 Personal (£84.99 per year) and use free LibreOffice (£0), saving is £84.99 per year.

What to do after cancelling Office 365

Access and expiry

After cancellation you will typically retain access until the end of the paid billing period shown in Services & subscriptions. If you received a refund access may end immediately. Save or export files before expiry.

Data export and mailbox

Download important files from OneDrive and export emails from Outlook. After cancellation cloud storage may revert to free limits: OneDrive reduced to 5 GB and Outlook.com to 15 GB. Shared users on Family or Premium lose increased storage allowances when shared subscription ends.

Re-activation

You can re-subscribe at any time by purchasing a new plan. Re-activation may require signing in and choosing a plan. Any promotional pricing previously used may not be available.

Next steps and practical checklist

Use this checklist to cancel Office 365 cleanly and secure your data.

  • Sign in to account.microsoft.com and check Services & subscriptions for the renewal date.
  • If purchased in-app, check Apple App Store or Google Play subscriptions and cancel there.
  • Decide whether to ask support for a retention offer; save any written offer.
  • Export OneDrive files and back up Outlook mailboxes before the subscription end.
  • Keep proof of cancellation: screenshot of cancellation page and any confirmation email.
  • If you paid by card and dispute a refused refund, contact your card issuer for chargeback or Section 75 if applicable.
  • If you need to send a written cancellation, use registered post to: Office 365, Crown Way, CF14 3UZ Cardiff, United Kingdom.
