transferring email from gmail.com to outlook.com since trueswitch went offline

Hello there,

I am trying to COPY emails from gmail.com to outlook.com. Microsoft articles that I've found say to use "Trueswitch," but the link given, as well as going to "trueswitch.com" results in an error message indicating that the service has gone offline.

I know that gmail has a built-in way to migrate messages from one account to gmail; I was wondering if outlook.com had this or if there was another way to get the messages from gmail.com to outlook.com.

Thanks!
