You'll be asked for the following information when you sign up
The address and contact information for your subscription:
Country where the services will be used. You won't be able to change the country later, even during the sign-up process; you'll have to restart the sign-up wizard.
Email and phone number so we can contact you if needed about your subscription. For example, if you forget your password, we would use this information to send you a temporary one. We also send your billing information to the email address you specify.
The email address you enter here is different from your Microsoft 365 email address (your logon name, below). Because this is where we also send your billing information, we recommend you use an e-mail address that's appropriate for receiving business email.
A sign-in name (user ID): This user ID becomes your initial Microsoft 365 email address, just to get you started quickly.
This user ID is the email address that you use to sign in. For example, if your business name is Fourth Coffee, you might choose email@example.com for your user ID.
Most people add their own custom domain shortly after they sign up so they can start getting email to it. For example, if you have a custom domain named fourthcoffee.com, you can set up your email address as firstname.lastname@example.org.
You can pay for your subscription with a credit card. If the cost reaches a certain amount, you may also have the option to pay by invoice.
When you sign up, be sure to choose the best payment option for your organization. Changing payment options involves calling billing support.
