☁️ Microsoft 365 Administration
Provide daily administration and support for Microsoft 365 environments in a Managed Service Provider (MSP) setting, helping business clients manage identities, licensing, Exchange Online, and security.
Overview
As part of my day-to-day work at an MSP, I administer Microsoft 365 environments for a range of business clients. This covers the full identity and licensing lifecycle — provisioning new users, assigning and reclaiming licenses, managing Exchange Online mailboxes, and configuring multi-factor authentication and conditional access to keep client environments secure.
Because each client has different needs, this work also involves troubleshooting mail flow issues, resolving sync problems between on-prem Active Directory and Entra ID in hybrid environments, and documenting changes so the rest of the team has visibility into what was done and why.
Technologies Used
- Microsoft 365
- Exchange Online
- Entra ID
- Active Directory
- Microsoft Intune
- PowerShell
Highlights
- Administer Exchange Online mailboxes, distribution groups, and mail flow rules.
- Manage Entra ID identities, MFA, and conditional access policies.
- Handle Microsoft 365 licensing across multiple client tenants.
- Provision and deprovision user accounts as part of onboarding and offboarding.
- Troubleshoot hybrid identity sync issues with Entra Connect.
- Write PowerShell scripts to automate repetitive administrative tasks.
Challenges
- Working across many client tenants, each with different configurations and policies.
- Diagnosing mail flow and delivery issues in Exchange Online.
- Troubleshooting Entra Connect sync errors in hybrid environments.
- Balancing security requirements (MFA, conditional access) against client usability.
What I Learned
This work has given me a solid, practical understanding of identity and licensing management at scale, and reinforced how much of good Microsoft 365 administration comes down to consistent process and documentation across many different environments.
