Sometimes Kmail2 seems to be "out of sync" with the mail server IMAP account, despite the system being online. When this happens, and I click on "Fetch mail" or "Update view", nothing at all happens. Reproducible: Always Steps to Reproduce: 1. Wait until KMail2 is out of sync with the online folder. (This usually happens after a few hours with an unreliable internet connection.) 2. Click on a command that should bring the folders back in sync. Actual Results: Nothing happens. Expected Results: EITHER (a) synchronise everything because the computer is online and I gave KMail2 the command explicitly to do so, OR (b) Show a message why KMail2 decides to ignore my command. (Or at least when I click on the "Fetch mail" command in the menu, then the progress indicator should come up and tell me that something is happening.)
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present? If noone confirms this bug for a Framework-based version of kmail2 (version 5.0 or later, as part of KDE Applications 15.12 or later), it gets closed in about three months.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
