Phone/Outlook not receiving mail

Hello - I got a random email that said I reset my password (which I did not).  I immediately changed my password for real.  I can now access my account and I turned on two-factor authenticaton.  Problem is I cannot receive e-mails on my phone or in Outlook.  I have changed the settings in both to reflect the new password.   Is there a global issue with third party email apps?

Thanks in Advance.
