I logged on yesterday and received a message that I need a verification code, It said it will send it to my email address on record, which is a gmail account, I said OK, but never got it. What is  going on?

I tried again today, resend it a few times but nothing is coming through.

I am now worried that in  a few days time I will get a message that I cannot logon at all because I have not verified the code, but I don't have the code.

Funny enough email was sent to my Gmail account verifying that "Confirm your email address for your Microsoft account" which I have done.
