can’t receive e-mails on laptop and iphone

I have not been able to receive emails into my outlook account for 5 days now. I can access them from my Virgin email account but not outlook, this has not been a problem before, it seems there is something stopping them from coming over. Also my partners iphone stopped receiving the same emails at the same time.  I contacted the Virgin tech team and their additional tech team but they could not fix it. This is extremely frustrating as it was never a problem before and my partner needs to access the emails for her job. Any help resolving this would be a great help, my email address is *** Email address is removed for privacy ***
