2.1. Core Objects and Admin Centers
š” First Principle: Every Microsoft 365 service has a primary object type it manages ā mailboxes for Exchange, sites for SharePoint, teams for Teams. Knowing the right admin center for each task isn't about memorizing menus; it's about matching the object you need to configure with the service that owns it.
Think of M365 admin centers as specialist departments: the Exchange admin center is HR for mailboxes, the SharePoint admin center is facilities management for sites, and the Teams admin center is IT for collaboration. You go to the right department for the right object.
| Object Type | Primary Admin Center | Common Tasks |
|---|---|---|
| Users & licenses | M365 admin center | Add users, assign licenses |
| Mailboxes | Exchange admin center | Shared mailboxes, mail flow rules |
| SharePoint sites | SharePoint admin center | External sharing, site policies |
| Teams | Teams admin center | Meeting policies, app permissions |
| Identity & access | Entra admin center | Conditional Access, PIM, groups |
| Compliance | Purview compliance portal | DLP, retention, eDiscovery |
ā ļø Exam Trap: Many tasks can be started in the M365 admin center but require the specialized admin center for full configuration. The exam tests whether you know which admin center has the complete feature set for each task.
When you're troubleshooting or configuring M365, the most common mistake is going to the wrong place. An admin who configures email security settings in the Exchange admin center ā rather than the Defender portal ā will apply the wrong policies, or find the settings simply aren't there. The admin center map is your navigation system.
This section matters every time you onboard a user, configure sharing, set up a team, or troubleshoot access. It's also heavily tested: expect scenario questions like "where would you go to accomplish task X?"
ā ļø Common Misconception: The Exchange Online admin center handles all email-related configuration. In reality, mailbox management lives in Exchange, but email security policies (anti-phishing, safe links, safe attachments) live in the Microsoft Defender portal.
