I update to latest version and still getting swiftmailer not working.

Alright, thanks for the update here. Let us know, your smtp outlook email is a micorosoft 365 email business or normal outlook email. If you are using the microsoft 365 business email then for this setup we have added few changes for modern auth.
So you will be setup with the v-1.2.0 version of uvdesk using the below command:

$ composer create-project uvdesk/community-skeleton:dev-master;
