Hello,
We are sorry to hear that your planning to cancel the subscription.
Yes you can still access msn email account after cancelling the subscription, You can continue to access email by going to http://www.hotmail.com/. Your email account will be converted to a "free" version of MSN/Hotmail email. Once your account becomes free you will no longer have the benefits of McAfee Antivirus or the SpySweeper from Webroot as they are part of the MSN subscription. Ffor any technical issues in future you have to get in touch with online service which is https://answers.microsoft.com/
Please check the private message for MSN Accounts and Billing number to get assistance
Note : Please sign in with your MSN email address and password to check the private message
Thanks
Jason
