Microsoft 365 Management, Security and Support for West Michigan Businesses
If your business runs on Outlook, Teams, SharePoint and OneDrive, Microsoft 365 is where your files, client conversations and logins live. For most Grand Rapids organizations, it was set up once and has been accumulating loose ends ever since.
Alliance Tech provides Microsoft 365 services in Grand Rapids that cover the whole tenant: cleaning up what is already there, locking down who and what can connect, and handling day-to-day administration from our office on Kenmoor Ave SE.

What We Find in Grand Rapids Microsoft 365 Tenants
Most of the risk in Microsoft 365 builds up over years of normal use. Staff come and go, sites get created for one project and forgotten, and phones get added without anyone deciding how they should be managed.
- Mailbox rules forwarding mail outside the company. External forwarding is a common sign of a compromised account or an insider problem, and it often goes unnoticed for months.
- Former employees whose mailboxes are still accessible. Without a formal off-boarding process, accounts stay active and shared mailbox permissions keep piling up.
- Client files in personal OneDrives. Sensitive documents end up in individual accounts or loosely controlled SharePoint sites, where the business has little visibility.
- Teams and SharePoint sites with no owner. Sites spun up for a single project keep broad permissions and external guests long after the work is done.
- Phones reading company email with no controls. Personal devices with full mailbox access and no app protection policy mean company data leaves with the device.
- Security policies that exist but get bypassed. Conditional Access rules that fail constantly usually mean users have found a way around them.
Our Microsoft 365 Services
Tenant Review and Cleanup
We start with a full review of your tenant: admin roles, licensing, mailbox rules, external sharing links, guest accounts, inactive users and current security settings. You get a prioritized list of what we found, and we fix the urgent items first.
For organizations moving off on-premises Exchange or file servers, we plan the migration around that cleanup so old problems don’t come along for the ride. Our cloud services page covers migrations and Azure in more depth.
Identity and Device Controls
We separate privileged admin accounts from everyday logins, enforce MFA for every user and app, and build Conditional Access policies around device compliance, location and sign-in risk. Using Intune, we manage company-owned devices and apply app protection policies to personal phones, so company data can be removed without touching personal photos or texts.
SharePoint, OneDrive and Teams Governance
We restrict external sharing to approved domains, set expiration dates on outside links, assign owners to every site and team, and review permissions on a regular schedule. This is also how we prepare clients for Microsoft 365 Copilot, which can surface anything a user has access to. Getting permissions right before turning it on keeps it from exposing files that were overshared years ago.
Email Protection
We configure Microsoft Defender for Office 365 with Safe Links and Safe Attachments, tune anti-phishing policies to catch impersonation of your executives and key vendors, and set up SPF, DKIM and DMARC so your domain can’t easily be spoofed to your own clients.
Day-to-Day Administration
New hires get licensed, set up and added to the right teams before their first day. Departing employees are removed through a repeatable off-boarding checklist that covers mailbox access, shared files and devices. Licensing, password issues and Teams problems go through our Grand Rapids help desk.
Monitoring and Audit Logging
We confirm the Unified Audit Log is enabled and retained for as long as your obligations require, then watch for unfamiliar sign-in locations, new forwarding rules and unusual mailbox activity. Our SOC treats those events as security incidents, with a documented record of what was found and what we did.
What’s at Stake in Microsoft 365
Business email compromise drove the bulk of corporate cybercrime losses in the FBI’s 2025 Internet Crime Report, with just over $3 billion in losses across 24,768 reported incidents.
Stolen logins remain a common thread. The 2026 Verizon Data Breach Investigations Report found that 38 percent of victims of opportunistic attacks had compromised credentials in circulation. Identity controls and sign-in monitoring are where we focus first for that reason.
Microsoft 365 for Grand Rapids Industries
Manufacturing
Plant floors often have shared workstations and staff who only need email, schedules and Teams. We set up frontline licensing and shared device access that fits those roles without handing out full accounts to everyone.
Healthcare Practices and Vendors
We configure Microsoft 365 to support HIPAA requirements, including data loss prevention for patient information, encrypted email and access controls that match staff roles.
Financial Services Firms
RIAs, CPAs and wealth managers need email retention aligned to their regulatory timelines, data loss prevention for account numbers and Social Security numbers, and anti-phishing tuned for spoofed custodian brands. We recommend Business Premium as the minimum license for these firms, because Standard leaves out most of the security controls that matter.
Why Grand Rapids Businesses Choose Alliance Tech for Microsoft 365
We treat Microsoft 365 as part of your security program. The same team that manages your tenant also runs your cybersecurity services in Grand Rapids, so a risky sign-in or a strange forwarding rule gets acted on instead of sitting in a report.
We also document every policy decision, which gives you clear answers when a client due diligence questionnaire, cyber insurer or auditor asks how your data is protected.
And because our office is local, rollouts, training sessions and hands-on fixes happen in person when that’s the better option. See how Microsoft 365 fits into our full range of IT services in Grand Rapids.
Frequently Asked Questions
Can you take over a Microsoft 365 tenant someone else set up?
Yes, and most of our clients come to us that way. We start with a tenant review, document what we find and fix the urgent items before moving into ongoing management.
Is our data ready for Microsoft 365 Copilot?
It depends on your permissions. Copilot can surface anything a user can already reach, so we review SharePoint, OneDrive and Teams access first and tighten oversharing before it is turned on.
Can we control company email on personal phones?
Yes. App protection policies in Intune let us secure Outlook, Teams and OneDrive on personal devices and wipe company data if a phone is lost or an employee leaves, without managing the whole device.
Do you work with our internal IT person?
Yes. We can handle Microsoft 365 security and administration while your internal staff keep other responsibilities. Our co-managed IT services explain how that works.
