Created attachment 157227 [details] Failed to append item Hello, recently I have the problem that no mails are received. I've attached the debugg file from the Akonadi console, this might help.
maybe important, the bottom left of the status bar says the following: Unable to fetch item from backend (collection -1) : Unable to retrieve item from resource: Unable to write item changes into the database
this help for status bar: https://docs.kde.org/stable5/de/kmail/kmail2/you-get-the-error-unable-to-fetch-item-from-backend-when-entering-imap-folder.html
I've the same problem. I cannot even edit existing addresses. ("Unable to write item changes into the database")
In my case the solution was to downgrade several packages via: sudo apt install mariadb-common=1:10.5.18-0+deb11u1 mariadb-server-core-10.5=1:10.5.18-0+deb11u1 mariadb-client-10.5=1:10.5.18-0+deb11u1 libmariadb3=1:10.5.18-0+deb11u1 mariadb-client-core-10.5=1:10.5.18-0+deb11u1
