How to disable the function of duplicating sent emails from mobile mail to regular mail?

Question

Yandex

When sending letters from Yandex mobile mail, the sent letter is duplicated and appears in the inbox on a regular computer, for example, in outlook. However, these duplicates are not included in the browser version of Yandex mail.
Mail connected via POP in outlook. What to do and how to be to get rid of these duplicates in outlook?

Answer 1

By and large, some kind of surrealism in the situation. I would suggest connecting via IMAP4, this will kill two birds with one stone, the mail will remain on the server (because apparently it stays there for you) and in general, an annoying error will probably disappear. Well, IMAP4 is just designed for such work with mail, unlike the outdated POP3.

Answer 2

What if I don't want to store emails on the server? There the box is limited to 10 gigabytes + not safe if the box is hacked + other reasons. I just want to store mail locally. In this case, if you save sent messages on the computer, the sent messages are duplicated in the Sent folder, although the Sent folder (on the computer) is selected. This is most likely a long-standing glitch in Outlook, since for some reason it duplicates sent messages in the IMAP sent folder, but should save them in Sent Items (on the computer) - the folder is lower in the hierarchy. Also, if you create rules for moving incoming letters, then Outlook also starts duplicating incoming letters, and at the same time, sent letters begin to be duplicated in the inbox (the rule is triggered by email)! It's just the curvature of Outlook and the illogicality of the people who develop it and cannot fix it for years.
