Set up PlusNet IMAP email on New Outlook but emails stopped downloading ...

[#1]

Hi everyone, I successfully set up the above recently and my Plusnet emails immediately downloaded but, since then, they have stopped coming through.  I've tried re-installing a few times and new ones (occasionally) appear.  There is obviously some sort of conflict somewhere, but I've no idea how to fix this. I do not have an Office 365 subscription and am not technically minded at all. 

Has anyone got any ideas  Thank you ...

@Mimi  Welcome to the Plusnet Community Fora.

Have you logged in to web mail and confirmed that any missing emails are present there?

Yes, they are there, but I like the Outlook appearance and like to keep all my email addresses in one place.

Anyone else experienced this, or have any ideas on how to fix the problem?  Thanks;

I have the same problem on my PC.
