[TW] What is akonadi? Can I get rid of it?

I have just installed Tumbleweed on a new partition. I previously used (and still have available) Leap 15.4. I am new to TW, and want to try it out. In Tumbleweed, akonadi_davgroupware_resource_6 keeps asking for a kwallet password. I have never used kwallet, so I don't have a password to enter. I seem to remember tabooing akonadi a long, long time ago, but I can't remember which files to taboo. I do not use kontact, kmail, kaddressbook, knotes etc. Kleopatra is useful, but I can live without it. Regards Bob -- Bob Williams
