@Berny Apologies for the delay in getting back. Nothing I could see in the logs. I had noticed that the first attempt to connect to the POP account failed but if I clicked on ‘download’ a second time it connected and downloaded emails. I’ve made the changes you suggested (new areas of Kaspersky I’ve not been into before, and been using it every year since 2013!) and the connection works first time, every time. Weird? But resolved. Many thanks
