Activation confirmation message-
An activation confirmation message is a system-generated email sent by Microsoft Online Services (such as Microsoft 365 or Azure Active Directory) after a user’s account has been successfully created and activated. It serves several important purposes in the onboarding and authentication process.
Key contents of the message-
- Account activation confirmation – Notifies the recipient that their Microsoft Online Services account is now active.
- Username (User Principal Name) – Typically in the form
user@domain.com, this is the credential the user will use to sign in. - Temporary password – A system-generated password for the initial login. The user is usually prompted to change this upon first sign-in.
- Logon instructions – May include a link to the login page (e.g.,
https://portal.office.com) and basic steps for signing in.
Purpose and importance-
- Acts as a trigger point for new users to begin using Microsoft services (e.g., Outlook, Teams, SharePoint).
- Ensures security and access control, since only the user who receives the message can log in and change the temporary credentials.
- Supports IT administrators during bulk user onboarding, particularly in enterprise environments.
When it’s sent-
- After an administrator adds a user through the Microsoft 365 admin center or via PowerShell scripts.
- During automated provisioning from systems like Azure AD or third-party identity platforms.
