Sent mails are duplicating in Microsoft-based email accounts, one per recipient, plus one created by Mailspring.
Testing Notes
This needs to be tested with Outlook accounts. There are plenty of reporters who can verify the fix (as can I).
Tips
The code responsible for moving mail to sent is in Mailspring-Sync/MailSync/TaskProcessor.cpp:1442-1536. I’m going to dig into a bit, and see if I can figure out what’s going wrong, as it is supposed to prevent duplication of sent messages.
