Hi,
I’m on Fedora KDE 41. I accidentally clicked on Kontact and was presented with “Account Assistant” to set things up for me, but I was not ready for it so I closed it. However, now I cannot figure out how to get that account assistant back (it only comes up the first time you click the application). Can someone please help me with how to get that assistant back? (I checked the system settings options but they are different). Thank you.
Yes. Open Kontact, go to KMail and choose “Settings” > “Add Account…” and the assistant will pop up.
Thank you so much! I was just about to reformat my system because of it, you have saved me so many hours! 
Ach! There is hardly ever a reason to re-format! In the worst case, when something like this happens, you can reset stuff by removing or renaming a couple of files. Ask here first!
I wish I had discovered KDE discuss earlier. I will surely do so from now. Thank you so much again!
