+### -Password
+The Password parameter specifies the password that's required to open the exported message.
+
+You can use the following methods as a value for this parameter:
+
+- `(ConvertTo-SecureString -String '<password>' -AsPlainText -Force)`.
+- Before you run this command, store the password as a variable (for example, `$password = Read-Host "Enter password" -AsSecureString`), and then use the variable (`$password`) for the value.
+- `(Get-Credential).password` to be prompted to enter the password securely when you run this command.
