You can remove the file, and dovecot will notice it's absence and update it's indexes if this is maildir++ format.<br><br>If this is sdbox, you need to run `doveadm force-resync -u user FolderName`.<br><br>Aki<br><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #ad7fa8; padding-left: 1ex;">On 16/03/2022 12:08 Joachim Lindenberg <dovecot@lindenberg.one> wrote:<br><br> <br>Hi Aki,<br>sure I can delete (or rename) the file(s) in the mail directory. <br>Will sync then restore it from remote or should I do this manually?

Not much you can do about it other than maybe delete the file? You can try recover it with `doveadm fetch -u someone text uid 1553 mailbox Sent` and then using `doveadm save -u someone -m Sent` to store it back.<br><br>Aki<br><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #8ae234; padding-left: 1ex;">On 16/03/2022 09:35 Joachim Lindenberg <dovecot@lindenberg.one> wrote:<br><br> <br>Nobody that can help?<br>Thanks,<br>Joachim<hr>I am still experiencing the issue.
