This bug has never been confirmed for a KDE PIM version that is based on KDE Frameworks (5.x). Those versions differ significantly from the old 4.x series. Therefore, I plan to close it in around two or three months. In the meantime, it is set to WAITINGFORINFO to give reporters the oportunity to check if it is still valid. As soon as someone confirms it for a recent version (at least 5.1, ideally even more recent), I'll gladly reopen it. Please understand that we lack the manpower to triage bugs reported for versions almost two years beyond their end of life.
Yes, still reproducible with KDE Applications 16.12.3 and KDE Frameworks 5.36.0.
This still happen on KDE Frameworks 5.38 and Kmail 5.6.1.
That happen too if you sleep the PC and wake up it.
I’ve just had this happen to me with packages from latest Ubuntu (version 5.15.1 or 20.08.1). Last night as I was going to sleep some problems started occurring with my Internet connection. Today it was fine again, but new emails stopped coming into one account. If I tried to synchronize it in KMail, nothing would happen at all, the status bar would not display any activity. If I tried to synchronize all accounts, only the other one would work, completely ignoring the first one. In akonadiconsole, the account was shown as Ready, but synchronizing it there likewise did nothing. I’m sorry to say this, but Akonadi has been with us for more than ten years, and all this time it Just Does Not Work in the most inappropriate way, by silently stopping to receive messages at most inopportune moments. Could you please either fix the underlying issue once and for all, or at the very least make it display a very prominent message should it lose the connection?
