You can also remove an account from your device. This doesn't delete the account, but it does remove email and other content associated with the account from your device.

To remove an email account:

Select the Start button, and then select Settings > Accounts > Email & accounts .

Open Email & accounts settings

Under Accounts used by email, calendar, and contacts, select the account you want to remove, and then select Manage.

Select Delete account from this device.

Select Delete to confirm.

To remove an account used by apps:

Select the Start button, and then select Settings > Accounts > Email & accounts .

Under Accounts used by other apps, select the account you want to remove, and then select Remove.

Select Yes to confirm.

After you close your account

When you select the Mark account for closure button, we wait 60 days before permanently deleting your Microsoft account in case you change your mind or need to access something on the account before it’s gone forever.

During the waiting period, your account is marked for closure but it still exists. If you want to reopen your Microsoft account, just sign in again within that 60 days. We’ll cancel the account closure, and everything will be just as you left it.
