Yes it is my fault.
Having used hotmail.com for over a decade, it was not easy to switch to other providers like gmail.com.
Little did I know that my laziness would come back to haunt me on an important business trip.
Once I left Korea and arrived in a different country, hotmail.com would not allow me to access my account. It continuously asked me to go through a cumbersome verification process. But even when I completed the process it did not work. It simply told me that the process could take up to 24 hours. I tried to find the contact details of Mircosoft's Customer Service - to no avail. It was probably one of the most frustrating and infuriating experiences. When I tried clicking on what I imagined to be the link to Customer Service, it sent me back to hotmail.com's landing page!!
In the end, I was not able to access my hotmail account and had difficulty conducting my business affairs.
When I came back to Korea, I was able to access my account without any trouble. And the below is one of the emails that I received from the Microsoft account team.
We detected something unusual about a recent sign-in to the Microsoft account ******@hotmail.com. To help keep you safe, we required an extra security challenge.

If this was you, then you can safely ignore this email.
If you're not sure this was you, a malicious user might have your password. Please review your recent activity and we'll help you take corrective action.
Since then I have been migrating to gmail.com.
I recommend others to do the same.
