Closed account
Closing your account
When you close your Microsoft account (the email address and password you use with Outlook.com) your email and contacts are deleted from our servers and cannot be recovered. The email address will be released 60 days after you close the account and can then be used by someone else. If you use your MIcrosoft account with other MIcrosoft services, you will no longer be able to access them.

To keep your Outlook.com account active you must sign in to the account at least once every 365 days. After 365 days of inactivity, your email will be deleted and cannot be recovered. After 2 years of inactivity, your Microsoft account will be deleted and cannot be recovered.
