Microsoft 365 needs an operating owner, not only a subscription. BTI Communications Group, LTD. plans, procures, migrates, configures and supports email, Teams, SharePoint, OneDrive, identity, devices and the security controls around them. The design connects licensing to real roles and workflows, establishes the cutover and recovery plan, and gives your team a documented path for administration after launch. Project-only, co-managed and fully managed scopes can be evaluated.
Professional offices, manufacturing, logistics, medical organizations and public-sector sites
Tell us the site or workflow, the current system and the outcome you need. Sales inquiries get a reply within one business day.

BTI Communications Group, LTD. provides Microsoft 365 migration, licensing guidance, security configuration and managed support in DuPage County. With Over 40 years in business, BTI combines Microsoft administration with network, voice, cybersecurity and governed AI expertise. A readiness review maps users, mailboxes, files, identity, devices and business dependencies before the migration or management proposal is written.
The assessment addresses a defined installation, a problem to fix or an ongoing operational need. Professional offices, manufacturing, logistics, medical organizations and public-sector sites are considered through their actual site, information and workflow requirements, not through a generic package.
| Service or system | Scope to confirm before implementation |
|---|---|
| Exchange Online and email migration | Inventory mailboxes, shared mailboxes, aliases, contacts, calendars, mail flow, domain ownership and applications that send email. Stage the move and define reconciliation checks before changing routing. |
| SharePoint, OneDrive and Teams | Choose where team records and personal work files belong. Design permissions, external sharing, ownership, sync behavior and retention with the organization rather than copying an old file-server layout blindly. |
| Entra ID and Intune | Scope authentication, role separation, onboarding, offboarding and device enrollment for the actual licensed features. Conditional Access and device policies are designed around supported clients and recovery needs. |
| Defender, Purview and email security | Review the security and governance capabilities included in the selected licenses. Configure the agreed policies, alerts, administrative roles and escalation path; a subscription name alone does not establish compliance. |
| Teams Phone and Teams Rooms | Assess voice and room requirements alongside networking, devices and licensing. Calling plans, Operator Connect or Direct Routing are evaluated for the actual environment, not assumed interchangeable. |
| Azure, backup and Copilot readiness | Review applications and identity dependencies, test recovery requirements and examine data permissions before AI access expands. Cloud availability, retention and backup recovery are separate design questions. |
From engineering to continuing service
Define the operating requirements, infrastructure and acceptance checks before choosing the equipment or licenses.
Review equipment, labor, licensing, assumptions and exclusions together. Compare the complete scope rather than a headline price.
Test the agreed workflows, train your operators and document the configuration and escalation route.
Map identities, source systems, mail flow, applications, data ownership and the information each role needs. Record unsupported clients, device restrictions and the point at which the client approves the target permission model.
Separate subscriptions, migration tooling, configuration, security work, device enrollment, training and ongoing support. Show which capabilities are already licensed and which need an upgrade, instead of charging for overlapping products without explanation.
Compare the license mix against user roles, security needs and existing purchases. Explain term and renewal responsibilities, included services and exclusions. A readiness review should establish when a migration is appropriate and when cleanup can improve the existing tenant.
Stage a representative pilot, validate content and permissions, agree on the cutover and rollback criteria, then support users through the transition. Reconcile mailboxes, files, application access and device enrollment before retiring the source system.
Manage joiners, movers and leavers, license changes, approved sharing, security alerts and service updates. Document which tasks belong to BTI, your internal IT team, Microsoft or an application vendor, with a clear escalation route.
A DuPage proposal should identify the owner of each dependency: the tenant, property manager, internal IT team, carrier, application provider or BTI. A local office does not remove the need for circuit delivery, room access, approved maintenance windows or the right decision-maker at commissioning. Confirm whether the project affects one suite, an entire building or a multi-site standard. Document which tests can occur during occupancy and which need a separate window. When outdoor work is required, plan for access and weather constraints rather than advertising a generic completion promise.
| Buyer intent | How it enters the plan |
|---|---|
| New installation | Define the required result, system boundaries, site or data access, implementation plan and acceptance tests before purchasing. |
| Repair and service | Identify the actual fault, affected workflow and support status before proposing a replacement. |
| Maintenance | Agree on checks, configuration records, user or device changes, renewal ownership and corrective work in the service scope. |
| Upgrade | Review compatibility, lifecycle, capacity, security and migration requirements; retain equipment or configuration that remains suitable. |
| Takeover or switching provider | Confirm ownership, access, documentation, existing agreements and provider release requirements before changing operational responsibility. |
| Monitoring and management | Specify the alerts, operational owner, escalation, reporting and change approval included. Technical monitoring is not an unlimited response or arrival guarantee. |
Calls are taken in real time, and client emails get a reply within 15 minutes. Client alerts are triaged in real time by enterprise-grade AI agents, then escalated to human engineers in the 24/7 NOC/SOC.
| Approach | When it fits | What to compare |
|---|---|---|
| Migration project | Move email or files, consolidate tenants or replace an unsupported platform. | Discovery, pilot, cutover, validation, training and source-system retirement criteria. |
| Tenant cleanup and security project | The service is live but roles, permissions, devices or licensing are inconsistent. | Prioritized remediation, approved configuration changes and documented ownership. |
| Managed or co-managed Microsoft 365 | Daily administration and security need a continuing owner. | Service responsibilities, escalation, license review and ongoing change management. |
The quote identifies one-time work, recurring services, subscriptions, retained equipment, assumptions, exclusions and third-party responsibilities. A repair, phased upgrade and replacement should be compared against the same accepted outcome, not only an equipment price. Final cost follows discovery; no entry price, unverified saving or fixed completion time is implied.
100% financing for parts, labor and licensing at 3.99% for five years. Financing and the itemized scope can be reviewed with your consultation.
The review starts with tenant and domain ownership, administrative recovery, user roles, mailbox and file volumes, applications, identity synchronization, devices and licensing. A representative pilot should include the difficult cases: a shared mailbox, a large library, an external collaborator and a business application that sends email. Acceptance checks reconcile content, test permissions and sharing, validate sign-in and device access, and confirm the recovery process. An old server is not retired because the copy job completed; the agreed checks and retention obligations must be satisfied first.
Microsoft operates the cloud service, while your organization still needs to decide how it governs access, retains records and recovers from mistakes or malicious change. Version history and recycle bins are not interchangeable with every backup requirement. BTI reviews recovery objectives and the chosen protection service, then tests representative recovery with the client. Retention, legal hold and backup policies are agreed separately. Compliance controls depend on licensing, configuration, operating practices and the governing requirements; no tenant is described as compliant merely because it uses Microsoft 365.
Operational continuity, shift handoffs and documented responsibilities.
Approved access, privacy and user workflows.
Procurement, retention and acceptance requirements defined by the organization.
DuPage planning is not a downtown Chicago project with the place name changed. Oak Brook and Lisle offices, Addison and Carol Stream industrial buildings, and public or medical facilities across the county have different occupancy, access and continuity needs. Projects are coordinated from BTI's Downers Grove office. Confirm landlord permissions, building access and the actual service address rather than assuming that a city name establishes county jurisdiction. Exterior installation and maintenance plans should account for seasonal conditions, safe access and the condition of the existing building systems.
The scenarios below are practical design considerations, not claims of named customers, completed local installations or measured savings.
An Oak Brook advisory firm or Lisle office can have years of shared mailboxes, guest access and files owned by former employees. Establish the authoritative records and the approved permission model before consolidation. Review external collaborators and the people who may approve sharing. A successful transfer is not enough if staff lose access to the correct client records or if an old personal account remains the only administrative recovery route.
An Addison manufacturer or Carol Stream distributor may depend on a mailbox, printer, scanner or application that ordinary office testing overlooks. Pilot those workflows alongside normal email and file access. Identify how shared work positions, turnover, mobile devices and sign-in policies will operate under the selected license mix. Keep production-system changes under their application or equipment owner instead of assuming a tenant project authorizes every connected device change.
For a Wheaton public organization or Naperville medical practice, collect the applicable procurement, retention and access instructions before selecting features. Map identities, devices, sharing, recovery and security escalation to those requirements. A cloud subscription is not a certification and an existing license may not include every desired control. The proposal separates entitlements, configuration work, user support and the responsibilities the organization retains.
Choose a representative mailbox, shared library, external collaborator and operating-site device. Reconcile content, test approved and prohibited access, confirm offboarding and validate a recovery example. Schedule the cutover around the client's actual operating needs and application dependencies, not a generic weekend promise. The handoff identifies who handles licenses, account changes, incidents, backup checks and future Microsoft service changes.

Get a free consultationBTI assesses the source platform, mailboxes, files, identity and application dependencies, then scopes a supported migration with a pilot, cutover plan, validation and user support.
Not necessarily. BTI reviews current subscriptions, user roles and the security or management capabilities required. The proposal identifies existing entitlements, gaps, terms and renewal ownership.
Yes, subject to an onboarding review of ownership, administration, recovery access, identity, security settings and existing agreements. Urgent risks and longer-term cleanup are documented separately.
Not automatically. Availability, retention, version history and backup recovery have different purposes. BTI reviews the recovery requirements and the selected protection service, including representative restore tests.
Teams Phone can be evaluated with the voice requirements, network, devices, carrier options and licensing. Number portability, emergency calling and any analog devices are checked before the cutover plan.
BTI can scope permissions, data ownership, sharing, identity and governance work before a Copilot pilot. AI access should follow approved information boundaries and licensing, not bypass them.
Yes. A co-managed scope defines who handles users, licenses, devices, security changes, recovery and escalation. The responsibility matrix is agreed before service begins.
BTI serves DuPage County from its Downers Grove office. The proposal defines remote and on-site responsibilities, access and implementation windows for the actual system or workflow. No arrival-time guarantee is implied by the service area.
Start with the business outcome, the current inventory or workflow, the known problems and the authorized decision owner. Local discovery addresses tenant, building, carrier and operating-owner responsibilities before an itemized proposal.
