To get access to a Azure subscription with an user account, the account must exist either in your Azure Active Directory (AAD) or as Microsoft account.
This blogpost is about a really annoying thing with Microsoft accounts used in Azure.
Let’s say you created a Microsoft account like firstname.lastname@example.org and you try to add it to a subscription in Azure and Azure won’t find it!
Strange isn’t it? First I thought that I had to register my @outlook.com-address as a Microsoft account in the same way like you do if you’re using a non-Microsoftbased e-mailaddress. But this wasn’t the case – you get the information that your outlook.com-account already is an Microsoft account.
So what’s the problem?
Microsoft accounts have a nice feature that make it’s possible to add other e-mailaccounts (aliases) to the actual Microsoft account and log in with those accounts to your Microsoft account.
The thing is that if one of those e-mailaccounts is selected as ”primary e-mailaccount”, it’s address becomes the primary account identifier!
Login at https://account.windowsazure.com and try to register for an Azure trial subscription, you will get some information about which e-mailaddress that is choosen as your Microsoft account:
So let’s try to add the alias address to the Azure subscription:
And the Microsoft (alias) account is successfully added to your subscription!
