Outlook 365 Desktop not sending Plus Net email

[#1]

Very recently Outlook desktop stopped sending from Plus mailboxes I have set up in my account. If I use webmail or Outlook on the web that works fine. I have reset the passwords on the mailboxes just be sure and also Outlook with no joy. I have spoken to Plus Net tech who have confirmed everything is working expect Outlook desktop. Any ideas please?

Oh no need to reply I've fixed this. It was a full repait on office but it actually removed the package for some reason so i had to reinstall.
