What is Managed Microsoft 365 Email?
DataComm Managed Microsoft 365 Email is a fully managed service for your Microsoft 365 Exchange Online environment. We take care of the design, security, configuration, and day-to-day administration of your email platform so your team can just…use email.
With DataComm Managed Microsoft 365 Email, we:
- Design and maintain your Microsoft 365 Exchange Online configuration and policies
- Manage user mailboxes, distribution groups, shared mailboxes, and aliases
- Implement and maintain security controls like MFA, conditional access, and anti-phishing
- Provide support for users and admins when email issues or changes come up
Instead of spending time on mailbox moves, DNS tweaks, spam issues, and endless admin tasks, you get a stable, secure email platform managed by DataComm.
Why do organizations choose Managed Microsoft 365 Email?
Email is still mission-critical—but managing it well is harder than it looks:
- Hybrid and remote work increase the reliance on cloud email and mobile access
- Phishing, business email compromise (BEC), and spam are constant threats
- Misconfigurations in Microsoft 365 can create security gaps or delivery problems
- IT teams are stretched thin and don’t always have time to dive deep into M365
DataComm Managed Microsoft 365 Email helps you get the most out of Microsoft 365 while keeping your environment secure, standardized, and well-documented.
How DataComm Managed Microsoft 365 Email works
We treat email as a core business service—not a side project.
Assess & Design
We start by understanding your current state:
- Review your existing Microsoft 365 tenant and Exchange Online configuration
- Assess domains, DNS records (MX, SPF, DKIM, DMARC), and mail flow rules
- Identify security posture, licensing usage, and any migration or cleanup needs
From there, we design a target-state email architecture aligned with your business and security requirements.
Implement & Stabilize
Next, we implement improvements and ensure a solid foundation:
- Standardize mailbox, group, and shared mailbox configurations
- Configure or refine security controls (MFA, conditional access, anti-spam/anti-phishing policies)
- Validate mail flow, connectors, and routing (including third-party integrations where applicable)
- Clean up legacy settings, unused objects, and risky configurations
The result is a clean, predictable Microsoft 365 email environment.
Operate & Support
Once your environment is stable, DataComm handles day-to-day operations:
- Provision and deprovision users, mailboxes, and groups
- Manage permissions, delegates, and shared mailbox access
- Troubleshoot delivery issues, client connectivity problems, and mobile access
- Support your users and IT team with email-related questions and requests
We become the email experts in your corner, so your team doesn’t have to be.
Secure, Optimize & Evolve
Email and threats both change over time:
- Monitor and tune security policies to respond to evolving phishing and BEC tactics
- Review reports and logs for suspicious activity and configuration drift
- Recommend and implement improvements (new features, better policies, or process changes)
- Align email services with broader collaboration tools in Microsoft 365 (Teams, SharePoint, OneDrive)
Your Microsoft 365 email stays secure, modern, and aligned with how your business works.
