Good to know
GOOD TO KNOW

This training course includes numerous exercises (60% practical) to enhance learning. Each session will take place even if only one person is registered (except in cases of force majeure). A preliminary interview is held between the participant and/or a company representative in order to fully assess the participant’s profile (level, needs, professional context, challenges, etc.).
Assessment : during the training course, the trainer assesses the participants’ progress through multiple-choice questions, role-playing exercises and practical work. Participants receive a certificate of completion at the end of the training course.

Objectives of the training: Microsoft 365 Troubleshooting and Expert Assistance Training Course
objectives of this Microsoft 365 Troubleshooting

By the end, each participant will be able to :

  • Administer and diagnose a Microsoft 365/Entra ID tenant : logs, roles, permissions, domains.
  • Manage and troubleshoot identities, users, groups, and licences.
  • Understand and resolve issues related to devices and access (Entra Join, Hybrid Join, guests).
  • Diagnose and repair incidents on Microsoft 365 services: Exchange Online, Outlook, OneDrive, SharePoint Online, Microsoft Teams.
  • Implement best practices for level 2/3 technical support for Microsoft 365 environments at the enterprise level.
Prerequisites of the training: Microsoft 365 Troubleshooting and Expert Assistance Training Course
Prerequisites
  • Basic knowledge of Microsoft 365 and the Office suite.
  • Ideally, prior experience in basic administration (users, groups, licences) in Microsoft 365.
  • Microsoft 365 administration environment and access to audit portals, logs and services to carry out practical exercises.
  • In addition, because each participant is unique, a personalised interview is conducted beforehand with our expert.
  • The purpose of this discussion is to design a training course that is perfectly aligned with the level, expectations and specific professional challenges of each learner.
Target audience of the training: Microsoft 365 Troubleshooting and Expert Assistance Training Course
target audience
  • Second/third-level IT support teams working on Microsoft 365
  • Microsoft 365 administrators wishing to develop their troubleshooting and professional support skills.
  • IT infrastructure or service managers responsible for ensuring the quality of service, reliability and continuity of Microsoft 365 environments.

FAQ
How do you troubleshoot Microsoft 365 issues?

Microsoft 365 troubleshooting follows a structured approach: confirm service health (admin center health dashboard), check user identity and licensing, validate conditional access and MFA, run targeted diagnostics (Microsoft Connectivity Analyzer, Teams call diagnostics, SaRA), inspect transport rules and message trace for Exchange, and pull diagnostic logs. MFE-IT trains administrators on this methodology applied to realistic incident scenarios.

Why is Microsoft 365 not working?

Common causes when Microsoft 365 ‘isn’t working’ include service incidents (check the Microsoft 365 admin center health page), license or licensing assignment issues, blocked sign-ins (conditional access, risky sign-in detection), DNS problems for hybrid setups, expired tokens, third-party tenant policies, or local network/proxy interference. The MFE-IT Microsoft 365 Troubleshooting training covers each cause with diagnostic playbooks.

What is the Microsoft Support and Recovery Assistant?

The Microsoft Support and Recovery Assistant (SaRA) is a free Microsoft tool that automates diagnosis and remediation for common Microsoft 365 issues — Outlook, Teams, OneDrive, Office activation, mobile setup. It scripts what would otherwise take many manual steps. Through MFE-IT’s hands-on approach, learners use SaRA on real issue patterns and understand its limits.

How do you check Microsoft 365 service status?

Microsoft 365 service status is checked in the Microsoft 365 admin center under Health > Service health (admin only) or on the public Microsoft 365 status page (status.office.com / health for advisories). The Microsoft 365 admin app on mobile also pushes incident notifications. Our MFE-IT training course on Microsoft 365 Troubleshooting covers proactive monitoring and alerting setups.
