Purchased Microsoft 365 on Sunday...cannot login in

Try this in order:

1. Use the Sign-in helper if Microsoft 365 will not accept the account or password.
2. Make sure the sign-in uses the same Microsoft account that was used to buy Microsoft 365.
3. If sign-in works, go to the subscriptions page and check whether the purchase is attached to that account: Sign in.
   • If the subscription shows Manage, Cancel, or Change payment, it is billed by Microsoft.
   • If those options are missing or limited, it may be managed by a third party.
4. If the subscription was bought through Apple App Store or Google Play, cancellation and refunds must be handled there. Microsoft cannot process refunds or cancellations for those third-party purchases.
5. If the subscription was bought directly from Microsoft and a refund is needed, cancel it first:
   • Go to Services & subscriptions
   • Select the subscription
   • Choose Manage > Cancel
   • During cancellation, Microsoft will automatically show whether the subscription qualifies for a refund.

Refund policy details supported here:

• In most cases, a refund may be available within 30 days of the initial purchase or before the first recurring billing date, whichever is sooner, by canceling the subscription.
• For the most recent recurring billing charge, cancellation within 30 days after payment may qualify for a one-time refund per Microsoft account, per subscription product.
• Not all cancellations result in a refund.

If the account still cannot sign in, use the sign-in helper first. If the refund does not appear during cancellation or sign-in cannot be recovered, use Contact Support from the Microsoft support pages.
