As you know, you can utilize Azure EA Portal to create new Azure subscriptions to charge from your EA contract. Microsoft will send an invitation mail to an account which your company has own. The account will be invited as Enterprise Administrator. Refer to an article below if you need to confirm each role on EA Portal.
Next, you need to invite accounts as new administrator roles. You have to confirm which account types are available to be invited, because there are two account types below.
- Microsoft Account
- Work or School Account
Difference of Auth Level on EA Portal
There are four types of "Auth Level" you can choose. Assume your organization has "normalian.xyz" Azure Active Direcotry tenant and here are diagrams which account types you can invite.
#1 You will find error messages below if you choose wrong Auth Level. Change proper Auth Level option to invite your accounts.
#2 Wizard to add new administrators will be changed like below.
#3 There is no effect for your existing administrator accounts even if you will change "Auth Level" after inviting the accounts.
#4 It seems to take a little bit time to reflect change of Auth Level, because it sometimes failed to invite new accounts just after changing Auth Level.
