SUMMARY It appears that the Akonadi IMAP resource aborts synchronisation with a server if a mailbox it is supposed to create already exists: When I try to synchronise one of my IMAP accounts from KMail, the synchronisation quickly aborts and on the console where ran `akonadictl restart` I see: org.kde.pim.imapresource: Failed to create folder on server: "Create failed, server replied: A000239 NO Mailbox already exists ( 0.001 + 0.000 secs ) . [ ALREADYEXISTS ]" It could be that the mailbox was created through another Akonadi IMAP resource on another computer, or it could have been created by the same Akonadi IMAP resource on this computer, but with it crashing during the sync. For examples of reports of the latter, see these bugs: * bug #418593 * bug #418595 * bug #418599 * bug #418912 STEPS TO REPRODUCE (assumption) 1. Create a new folder for an IMAP account using an Akonadi client 2. Have Akonadi go out of sync with the IMAP server 3. Have the folder already on the IMAP server, e.g. due to an incomplete sync 4. Try to synchronise the Akonadi IMAP resource with that same server OBSERVED RESULT * org.kde.pim.imapresource: Failed to create folder on server: "Create failed, server replied: A000239 NO Mailbox already exists ( 0.001 + 0.000 secs ) . [ ALREADYEXISTS ]" * Emails are not being synchronised to my computer EXPECTED RESULT * No error output in the console where I started `akonadictl restart` * Synchronisation with the IMAP server succeeds and the freshest emails are available for me on my computer SOFTWARE/OS VERSIONS Operating System: Gentoo Linux KDE Plasma Version: 5.19.2 KDE Frameworks Version: 5.71.0 Qt Version: 5.15.0

P.S. Expected behaviour on code-level: When the error is ALREADYEXISTS, Akonadi should consider the creation of the mailbox successful and continue the sync, i.e. mailbox creation should be idempotent.
Created attachment 129920 [details] kimap-20.04.2-create-alreadyexists-is-not-an-error.patch Attached patch fixes the issue in in KIMAP 20.04.2 by making CREATE and DELETE idempotent. If CREATE fails with an ALREADYEXISTS response code, that is not an error since the intended result (the object existing at the target location) has been achieved. Likewise, if DELETE fails with an NONEXISTENT response code, that is not an error since the intended result (the object being gone from the target location) has been achieved. Please note that for RENAME response code ALREADYEXISTS *is* an error since the content of the source folder was not moved as intended. cf. https://tools.ietf.org/html/rfc5530#section-3
