I resolved the duplicate messages issue by disabling by disabling the "Sent Messages Folder" in the Account Editor Defaults.

Date: Sun, 24 Feb 2019 11:37:11 +0000 We use outlook.office365.com as our mail server here at work. I am running Evolution 3.28.5 (3.28.5-2.el7) on my laptop under CentOS. Sending an email from my laptop results in a copy in my local Sent folder and one in the remote Outlook sent folder. I also use an Android for mobile Outlook mail. When I move the remote Outlook sent folder contents to my laptop local sent folder, sent messages are clearly shown duplicated. Ctrl-A and "Remove Duplicate Messages" results in the following: Folder “michael.duv...@concurrent-rt.com<mailto:michael.duv...@concurrent-rt.com> : Sent Items” doesn’t contain any duplicate message. Please advise. I think the issue here is "what makes a message a duplicate". I suspect, although I don't know without examining the code, that a duplicate is determined by the Message-ID header. Have a look at the source of the messages and you'll be able to see if the Message-IDs are identical.
