M365 Administration and Troubleshooting — Lesson 2: Exchange, Teams, SharePoint, and OneDrive Troubleshooting

Learning Objectives

• Explain and apply Resolve mailbox, mail flow, transport, spam, calendar, delegation, retention, and Exchange Online connectivity problems.
• Configure, perform, or evaluate Diagnose Teams meetings, calling, chat, apps, SharePoint sites, OneDrive sync, sharing, permissions, and content access.
• Validate the selected approach with documented requirements, evidence, risks, and measurable acceptance criteria.

Detailed Topics

• Core capability: Resolve mailbox, mail flow, transport, spam, calendar, delegation, retention, and Exchange Online connectivity problems
• Implementation workflow: Diagnose Teams meetings, calling, chat, apps, SharePoint sites, OneDrive sync, sharing, permissions, and content access
• Planning: prerequisites, stakeholders, dependencies, scope, assumptions, and expected outcomes
• Security and governance: identity, permissions, data protection, compliance, accessibility, and change control
• Operations: monitoring, logs, validation, documentation, support ownership, and continuous improvement

Guided Demonstration

1. Review the requirement, users, data, dependencies, permissions, risks, and expected result.
2. Demonstrate the relevant configuration, development, analysis, administration, or operational workflow step by step.
3. Capture settings, outputs, logs, screenshots, calculations, test results, and other useful evidence.
4. Compare the observed result with acceptance criteria and explain any corrective action.

Hands-On Activity

Complete a guided implementation scenario and preserve evidence of settings, outputs, and exceptions.

• Document assumptions, prerequisites, and the planned sequence before starting.
• Complete the activity and test normal, boundary, failure, security, and operational conditions.
• Record issues, corrective actions, reusable notes, and the next improvement priority.

Scenario Analysis

• Identify the business or technical decision that must be made.
• Compare valid implementation approaches and their trade-offs.
• Consider security, privacy, accessibility, performance, support, cost, and operational impact.

Troubleshooting Focus

• Separate symptoms from causes and collect evidence before applying a fix.
• Check configuration, data, permissions, dependencies, capacity, connectivity, and recent changes.
• Validate rollback, recovery, ownership, user impact, and business continuity.

Validation Checklist

• The requirement, scope, inputs, and expected outcome are clear.
• The selected design or configuration is documented and follows approved standards.
• Normal, boundary, failure, security, accessibility, and operational conditions are reviewed.
• The result is supported by evidence and the next improvement is prioritized.

Lesson Outcome

Learners can explain and apply Exchange, Teams, SharePoint, and OneDrive Troubleshooting in a realistic scenario and validate the result with documented evidence.
