As noted in another reply: it worked fine for me in the version you are 
using. In the Plasma5 version 5.1.3 I am using it is currently, to me, a 
disaster. Right now I am told I have about 600 unread email in an IMAP 
account that I very well know I may have 3 or 4....

and then it goes in to some kind of loop "redownloading". And I should 
not, as a user, have to "akonadictl this or that", edit .rc files, 
recreate accounts and so on.

the whole chain from plain maildir/mboxes and up to KMail itself is too 
fragile, there are too many things that can go wrong.

It looks like I will have to spend the weekend trying to recreate 
accounts and so on. The point is: I like Kmail, I really do. But a 
simple upgrade should not render it more or less useless
