kamail2 inbox folder problem

["Hans-J. Ullrich" <hans.ullrich@loop.de>]

Hi list,

I accidently deleted my inbox folder (I mean the special "inbox" aka 
"Posteingang") in kmail2. Now I cannot create a new one. 

How can I get it back without messing with my settings and other folders?

Thanks for any help!

Best regards

Hans
