Outlook mail - duplicated sent emails
Outlook email accounts save two times the email sent into the Sent folder. My other providers don't. (???)
Config: imapx+smtp (automatically installed by POP!_OS - because I started with the default mail client "Geary" before install Evolution. And so, registered those MS mails there - that connected all those ones to my Microsoft Account into the Online Accounts Options on my POP OS system settings).
I'm using the last version Evolution in flatpak format "3.38.4 (by Flathub.org)" and using Pop!_OS 20.10 64 bits.
Cheers,
Diego
