Microsoft 365 Support in Clarkston, GA

Microsoft 365 Support in Clarkston, GA: Secure Tenant Management from COMNEXIA

Clarkston businesses running Microsoft 365 face a specific set of configuration risks that generic IT support rarely addresses: improperly scoped admin roles, disabled multi-factor authentication on shared mailboxes, and SharePoint sites open to external sharing by default. COMNEXIA, headquartered in Roswell, GA and operating since 1991, delivers security-first Microsoft 365 support to organizations across DeKalb County and metro Atlanta. Every engagement starts with a tenant audit, not a sales pitch.

What a Microsoft 365 Tenant Audit Actually Covers

Before COMNEXIA configures or migrates anything, a technician reviews your existing tenant against a documented baseline. That baseline checks Microsoft Secure Score, reviews Entra ID (formerly Azure AD) sign-in logs for risky authentications, confirms that conditional access policies block legacy authentication protocols such as SMTP AUTH and IMAP where they are not operationally required, and verifies that Intune device compliance policies are enforced before granting access to Exchange Online and SharePoint. If your tenant was provisioned by a previous provider or self-configured, these controls are frequently absent or misconfigured.

Core Microsoft 365 Services COMNEXIA Manages

• Exchange Online: Mailbox provisioning, shared mailbox governance, mail-flow rules, anti-spam and anti-phishing policy configuration through Microsoft Defender for Office 365, and DMARC/DKIM/SPF record alignment verified against your DNS zone.
• Microsoft Entra ID: Conditional access policy creation and testing, named location configuration, MFA enforcement via Entra ID Authentication Methods, and Privileged Identity Management (PIM) for time-bound admin role activation.
• Microsoft Intune: Windows and mobile device enrollment, compliance policy creation, application deployment via Intune app packaging, and BitLocker encryption enforcement tied to Entra ID device compliance status.
• SharePoint and OneDrive: Site collection architecture, external sharing governance (setting sharing scope to "existing guests only" or "specific people" rather than "anyone"), retention label policy configuration, and sensitivity label deployment through Microsoft Purview.
• Microsoft Teams: Teams governance policy (who can create teams, guest access controls, channel meeting policies), calling plan or Direct Routing configuration for organizations replacing a PBX, and integration with Microsoft 365 Groups lifecycle management.

Migration and Cutover: How COMNEXIA Moves You to Microsoft 365

A staged tenant migration for a Clarkston business typically follows a defined sequence. COMNEXIA first provisions the new tenant and configures Entra ID, then runs a directory synchronization assessment if Active Directory is on-premises (determining whether Azure AD Connect or Entra ID Connect cloud sync fits the environment). Mail is migrated in batches using Microsoft's IMAP or hybrid migration tooling depending on source platform. DNS MX records are not cut over until a technician confirms mail flow, autodiscover, and OAuth modern authentication all pass validation. Post-cutover, COMNEXIA monitors the Entra ID sign-in log and Exchange Online message trace for 30 days to catch any orphaned legacy authentication attempts.

Microsoft 365 Support for Auto Dealerships Near Clarkston

Auto dealerships in the Atlanta metro, including those in DeKalb County, operate CDK Global, Reynolds and Reynolds, or Dealertrack DMS platforms alongside Microsoft 365. These DMS applications frequently request broad email and calendar API permissions, which must be reviewed against your Entra ID enterprise application consent policies. Under the FTC Safeguards Rule, dealerships are required to maintain an information security program that includes access controls and encryption standards covering customer financial data. COMNEXIA maps Microsoft 365 controls directly to Safeguards Rule requirements: Entra ID conditional access satisfies access control obligations, Microsoft Purview sensitivity labels address data classification, and Intune device compliance policies enforce encryption at the endpoint level. If your service drive or finance office uses a shared Windows workstation, COMNEXIA configures Intune kiosk mode or Windows Autopilot to standardize those endpoints before they access Exchange Online.

Ongoing Management: RMM, Patch Management, and Monthly Reporting

Microsoft 365 support does not end at deployment. COMNEXIA uses NinjaOne for remote monitoring and patch management across all endpoints connected to your tenant, ensuring that Windows quality updates and Microsoft 365 Apps for Business channel updates are tested and deployed on a documented schedule. Help-desk tickets are tracked through a structured ticketing system with documented SLA categories by issue severity. Each month, COMNEXIA delivers a written report covering Microsoft Secure Score changes, Entra ID risky sign-in events, Intune device compliance status, and any license changes that affect billing.
