There is the same problem while working with exchange server. Sometimes it fetches all headers from exchange but finally it stuck. There is a logs pertaining this problem in .xsession-errors: akonadi_imap_resource_4(725) RetrieveItemsTask::onExpungeDone: Expunge failed: "Expunge failed, server replied: A000006 NO The currently selected folder is READ-ONLY.

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.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.1 aka 15.12; preferably much more recent), please open a new one unless it already exists. Thank you for all your input.
