After I sent a mail I receive the notifications: Speichern fehlgeschlagen, die Serverantwort lautet: A000007 BAD Command Argument Error. 12 sometimes also after that: Die Verbindung zum Server ist abgebrochen. The mails are saved nonetheless. Setup is Akonadi/KMail 4:16.04.3-2 from Debian unstable with Exchange 2013 behind Nginx proxy. Akonadi/KMail is configured to store sent mail in IMAP folder on that account. Reproducible: Always Steps to Reproduce: 1. Have Exchange 2013, probably behind Nginx proxy. 2. Setup IMAP and SMTP. 3. Set it up to store sent mails in folder "Sent Items." 4. Send a mail. Actual Results: After I sent a mail I receive the notifications: Speichern fehlgeschlagen, die Serverantwort lautet: A000007 BAD Command Argument Error. 12 => Saving failed, server answer is: … sometimes also after that: Die Verbindung zum Server ist abgebrochen. => Connection to server aborted. In ~/xsession-errors I also get: kdeinit5: Got EXEC_NEW '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/smtp.so' from launcher. kdeinit5: preparing to launch '/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/smtp.so' Cannot pause an inactive timer "Der Name des Hosts ist keiner aus der Liste der für dieses Zertifikat gültigen Hosts" => THe name of the host is in not from the list of the hosts that are valid for this certificate. log_kimap: We asked for UID but the server didn't give it back, resultingFlags not stored. log_imapresource: Flag append failed: "Speichern fehlgeschlagen, die Serverantwort lautet: A000007 BAD Command Argument Error. 12 " => Saving failed, server answer is: … log_imapresource: Flag remove failed: "Speichern fehlgeschlagen, die Serverantwort lautet: A000008 BAD Command Argument Error. 12 " Database "akonadi" opened using driver "QMYSQL" And sometimes instead: log_kimap: We asked for UID but the server didn't give it back, resultingFlags not stored. log_imapresource: Flag append failed: "Speichern fehlgeschlagen, die Serverantwort lautet: A000011 BAD Command Argument Error. 12 " log_imapresource: Flag remove failed: "Die Verbindung zum Server ist abgebrochen." => Connection to server aborted. "Der Name des Hosts ist keiner aus der Liste der für dieses Zertifikat gültigen Hosts" kdeinit5: PID 8816 terminated. kdeinit5: PID 8822 terminated. (not sure whether the last two are related) Expected Results: No error message and no occasional connection abort.
I intend to try to access Exchange server directly instead of by proxy to determine whether its a proxy issue. I also created IMAP log. Here is what I think the relevant excerpt of it: C: A000022 SELECT "INBOX" S: * 380 EXISTS S: * 0 RECENT S: * FLAGS ( \Seen \Answered \Flagged \Deleted \Draft $MDNSent ) S: * OK Permanent flags [ PERMANENTFLAGS ( \Seen \Answered \Flagged \Deleted \Draft $MDNSent ) ] S: * OK Is the first unseen message [ UNSEEN 251 ] S: * OK UIDVALIDITY value [ UIDVALIDITY 14 ] S: * OK The next unique identifier value [ UIDNEXT 21544 ] S: A000024 OK SELECT completed.

Why Akonadi issues UID STORE mutiple times (I am no expert of IMAP protocol).
I have something similar. We using Exchange without any proxies.
Git commit 1302bbba09461574c57c8e21c740e3f157b4527c by Daniel Vrátil. Committed on 07/01/2017 at 12:37. Pushed by dvratil into branch 'Applications/16.12'. IMAP: don't start STORE job with no flags fromAkonadiToSupportedImapFlags() can filter out all the flags that we are trying to append/remove which leads to UID STORE command with not FLAGS attributes, which is not RFC conformant and is rejected by some servers.
