I use kmail ( version 5.5.2). I have it set up to download all e-mail as local IMAP(not stored on server) so that each message is a separate file on my PC. Hasn't been a problem in a long time. Recently, I've gotten some "ghostly" messages that I could not delete. There was a cryptic error message pointing at the akonadi database. >From searching the web, I found that there is a management program called akonadiconsole. It allowed me to solve my problems. Here is what I did and some notes on what I found. So, I downloaded and installed it. Note that it should be run as a user (not as root) to access that user's e-mail. The program opens with 5 windows. Top left is "Collection" which are the various folders that the e-mail is stored in. Top right doesn't have a title, but displays the "ID", "Remote Id" and "MimeType" of each message. What I found (your results may be different) is that the messages that I was having problems with did not have an entry in the MimeType column. I right clicked on a message without a "MimeType" and chose "delete". (once I select a message, the body of the message displays below the message list) The problematic message was gone. It took a very few minutes for me to go through my messages, and clean out the problems. WORD OF WARNING: This is a low level database access tool. Changes that you make are immediate, and not reversable. You can mess things up badly if you are not deliberate and careful. (I did not try to mess my stuff up to find out), so be very careful. Good luck, and best wishes, Mark On Saturday, February 17, 2018 4:07:27 PM EST charlie derr wrote: > Apologies if this turns out to be a duplicate message.
