E-mail Authentication not in inbox.
Ok, closed client and restarted, it sent an email which was received instantly and worked.
So it looks like the original authorisation email was not sent, is this a known problem/bug?
Update, received the original authorisation email.
Seems to be a problem either with hotmail or the authorisation email system.

I have seen delays in receiving emails, too, and I’m never sure if it’s the sender or the receiving email system. 
I am glad that you got the email and that all is well now.
