Office 365 Managed Services in Stonecrest, GA
Stonecrest businesses operating in DeKalb County face the same Microsoft 365 configuration pitfalls that affect companies across metro Atlanta: shared admin credentials, unlicensed guest accounts with broad SharePoint access, and Teams channels that bypass email archiving entirely. COMNEXIA, headquartered in Roswell, GA and serving Georgia businesses for 35 years, manages Microsoft 365 tenants so those gaps get closed before they become breaches or compliance failures. Call us at (877) 600-6550 to schedule a tenant assessment.
What Office 365 Managed Services Actually Covers
Managing a Microsoft 365 tenant is not the same as buying licenses and turning on defaults. COMNEXIA's service covers the full Microsoft 365 stack: Exchange Online mail flow and anti-spoofing policies (SPF, DKIM, and DMARC records configured and monitored), SharePoint Online site permissions and external sharing controls, OneDrive for Business retention policies tied to your Microsoft Purview compliance settings, and Teams governance including channel lifecycle management and meeting recording storage limits. Identity is managed through Microsoft Entra ID, including conditional access policies that enforce multi-factor authentication on every sign-in and block legacy authentication protocols that modern brute-force attacks rely on.
Device enrollment and policy enforcement run through Microsoft Intune. Every Windows endpoint that touches your Microsoft 365 tenant is enrolled, compliance-checked against a defined baseline (BitLocker encryption, OS patch level, firewall state), and blocked from Exchange Online if it falls out of compliance. Patch management runs through NinjaOne, giving COMNEXIA's technicians a single RMM console that correlates patch status with Intune compliance posture before any device accesses corporate data.
Migration and Tenant Cutover for Stonecrest Organizations
If your Stonecrest business is still running on-premises Exchange or a legacy hosted mail platform, COMNEXIA executes tenant migrations in documented stages. The process begins with a pre-migration audit: exporting mailbox sizes, identifying shared mailboxes and distribution lists, confirming DNS authority, and documenting MX record TTL values before any move. Staged mailbox migration batches move non-critical users first, validate mail flow, then cut over executive and operations mailboxes during a defined low-traffic window. MX records are switched with a 300-second TTL to allow rapid rollback if a routing problem appears in the first hour. Post-cutover, legacy SMTP connectors are disabled and Entra ID password hash sync or pass-through authentication is confirmed before the project is marked complete.
Why Stonecrest Auto Dealerships Need Managed Microsoft 365
Automotive dealerships in the Stonecrest area that use CDK Global, Reynolds and Reynolds, or Dealertrack dealer management systems handle non-public personal information (NPI) that falls directly under the FTC Safeguards Rule. The Safeguards Rule, effective June 2023, requires covered dealerships to implement access controls, encrypt customer data in transit and at rest, and maintain an incident response plan. Microsoft 365 touches all three requirements: Exchange Online carries customer financing and deal-jacket data, SharePoint stores scanned contracts, and Teams conversations routinely include vehicle identification numbers and partial SSNs shared between F&I and the DMS.
COMNEXIA configures Microsoft Purview Data Loss Prevention (DLP) policies specifically to flag or block outbound emails and Teams messages that contain SSN patterns or financial account numbers, reducing the risk of accidental NPI exposure. Entra ID Privileged Identity Management (PIM) limits who can access SharePoint libraries holding deal documents, with just-in-time role activation and an auditable access log that satisfies the Safeguards Rule's requirement for monitoring and access control documentation.
Ongoing Management: What Happens Every Month
- Entra ID sign-in log review for impossible-travel events, legacy authentication attempts, and failed MFA challenges
- Exchange Online message trace audit for any SPF/DKIM/DMARC failures and newly created forwarding rules (a common indicator of business email compromise)
- SharePoint and OneDrive external sharing report reviewed and any anonymous-link shares flagged for business owner approval
- Intune device compliance dashboard reviewed; non-compliant devices quarantined from Exchange Online until resolved
- License reconciliation: unused or unassigned Microsoft 365 licenses identified and reported to reduce monthly spend
- NinjaOne patch report confirming all Windows endpoints are current on Microsoft security updates within 14 days of release
- Monthly summary report delivered to your designated IT contact with open items, completed changes, and upcoming Microsoft feature rollouts that affect your tenant configuration
Serving Stonecrest and DeKalb County Businesses
COMNEXIA has served Georgia businesses from our Roswell headquarters since 1991. Stonecrest, as an incorporated city in DeKalb County, has a growing commercial corridor along Mall at Stonecrest and the surrounding business parks, and those businesses carry the same Microsoft 365 risks as any metro Atlanta organization without the large internal IT teams that can manage tenant hygiene daily. COMNEXIA functions as that team, with documented onboarding, a ticketing system for every help-desk request, and a named technician familiar with your tenant configuration.
If your Stonecrest organization is running Microsoft 365 without conditional access policies, without DLP rules, or without a documented admin account inventory, your tenant is exposed in ways that a single phishing email can exploit. Call COMNEXIA at (877) 600-6550 to schedule a no-cost Microsoft 365 tenant review and get a written list of the specific gaps we find.
