By default in Microsoft Online Services both in Exchange Online Standard and BPOS – the POP 3 is disabled.

To enable you have to either raise a Service request with Microsoft or you can use Powershell to make the changes yourself. Using Powershell will require admin credentials. Here are some simple Powershell commands to enable the POP3 in Microsoft Online Services
