Still duplication sent on outlook

Description

I known it a known issue but I still get duplicated sent/reply mail in outlook. I try to following the guide line here

Duplication of Sent Mail

This is a long-standing known issue with Microsoft/Outlook accounts — Outlook’s server automatically saves sent messages to Sent, but often does it very slowly. Mailspring thinks the server will not save a copy, and saves its own to ensure the sent message is not lost, resulting in duplicates. Workaround: Go to outlook.live.com (or Outlook on the web for work accounts) > Settings > Mail > Compose and reply > disable “Save copies of messages in the Sent Items folder”. This lets Mailspring manage…

But there no longer any option to disable “Save copies of messages in the Sent Items folder” in outlook website it self.

I trying to specific separate folder for SENT in mailspring app and it do not help. Are there any solution yet?
