Definīcija: A user account and associated credentials that is used to access Microsoft’s and 3rd parties’ business services, such as Office 365. Work or school accounts are usually assigned to end users by their organization (work, school, non-profit) and managed by the admin. However, some business services like Yammer support work or school accounts that were created by end users, without IT involvement. We sometimes refer to these accounts as “viral” AAD accounts but we don’t use this term externally. Work or school accounts are stored in Azure Active Directory (AAD) and managed by Microsoft on behalf of the organization. One of the key difference with a Microsoft account is that users don’t own the account and will typically loose access to it if they leave the organization. Other aspects like password policies are imposed by admins.
