March 17, 2021

I want to change the name of my tenant of Azure Active Directory.

Introduction

At sign-up for Office 365, i get Azure Active Directory (AAD) instance.
I set the tenant name as 個人. In the now, I'd like to change it.

Open Azure Portal.

Type new name in Name field.

When I changed the name in the property page, but new name wasn't reflected immediately.

In my case, it was reflected an hour later.
