#405 Duplicated drafts

[Marco De Vitis]

Hi, I'm using DavMail 6.0.1-3390 on Windows 10, Thunderbird 102.2.2 and I think the company server is Office365 (DavMail is configured with EWS protocol, URL https://outlook.office365.com/EWS/Exchange.asmx).

When I edit a message, each time the draft is saved (both automatically or manually) a new draft is created without deleting the old one.
So, every time I compose a long mail which I save often in draft while writing, I end up with tens of copies in my drafts folder :-(, which I then have to delete manually after sending the final version.
I checked the saved drafts in Thunderbird and they all share the same Message-ID.
Why does this duplication happen? How can I avoid it?
Let me know if more info is needed.
Thanks.
