The Password property specifies the password used to
          authenticate the user. This property is used as the default value for
          the Authenticate method if no password is specified
          as an argument.
          
          Refer to the AuthType property for more information
          on the available authentication methods. If you are using the OAuth 2.0
          authentication method, this property should not be set to the user's
          password. Instead, you should set the BearerToken
          property to the OAuth 2.0 access token issued by the mail service provider.
          Note that these access tokens can be much larger than your typical
          password and are only valid for a limited period of time.
          You can use the Password property to specify an 
          OAuth 2.0 bearer token. However, it is recommended that you use the
          BearerToken property instead of assigning it to this
          property. It will ensure compatibility with future versions of the
          control and make it clear in your code you are using an OAuth 2.0 bearer
          token and not a password. If the AuthType property
          specifies one of the OAuth 2.0 authentication methods, this property
          will return the bearer token.
