Microsoft 365 Support in St. Catharines
Microsoft 365 is where most St. Catharines organizations keep their email, documents, meetings and identities. That makes the tenant one of the most valuable assets the business owns — and one of the least frequently reviewed.
Griffin IT Group administers Microsoft 365 the way a core platform deserves: security configured deliberately, licensing matched to actual need, data governed and backed up, and support available when Outlook, Teams or file sync misbehaves.
Administration
Day-to-day Microsoft 365 management
A tenant left to run itself drifts: licences assigned to people who left, distribution lists nobody maintains, sharing links that never expire, and settings that were defaults in 2019.
- 01
Users, groups and licences
Accounts created and removed on a documented process, group membership kept meaningful, licences reconciled monthly so you are not paying for unused seats.
- 02
Mail flow and deliverability
Connectors, transport rules, SPF, DKIM and DMARC alignment, quarantine review and investigation when messages fail to arrive or your domain lands in someone's junk folder.
- 03
Shared mailboxes and calendars
Structured access for reception, accounts, intake and service addresses, using shared mailboxes and delegation rather than shared passwords.
- 04
Teams and collaboration structure
Team and channel design, guest access rules, meeting policies, recording settings and phone or calling configuration where it applies.
- 05
SharePoint and OneDrive health
Sensible site structure, permission inheritance that can be explained, sync troubleshooting, storage monitoring and version history settings.
- 06
Service health and change tracking
Monitoring Microsoft's own incidents and roadmap changes so unexpected behaviour is identified as a platform change rather than investigated as a local fault.
Tenant security
Securing the tenant beyond the defaults
The single most common weakness we find in Microsoft 365 environments is identity configuration: MFA applied inconsistently, legacy authentication still permitted, global administrator rights spread across several everyday accounts, and audit retention left at the minimum.
We work through the tenant methodically — Entra ID policy, Conditional Access, privileged role assignment, Defender for Office 365 policy, device compliance through Intune, external sharing rules and alerting — and document the resulting configuration so it can be reviewed rather than rediscovered.
- MFA enforced for every account
- Legacy authentication blocked
- Conditional Access by user, device and risk
- Global admin separation and just-in-time access
- Defender anti-phishing and Safe Links policy
- Mail forwarding and rule alerting
- Device compliance requirements
- External sharing and guest governance
- Audit log retention
- Sign-in risk alerts and review
- Data loss prevention rules
- Regular configuration drift checks
Migration
Migrations that finish without a difficult week
Most Microsoft 365 migrations we handle in St. Catharines fall into a few categories: moving from an on-premises Exchange server, leaving a hosted email provider, consolidating two tenants after an acquisition, splitting a tenant after a business separation, or finally moving a file server into SharePoint and OneDrive.
The technical work is well understood; the risk lives in the details. Mailbox sizes and shared calendars, public folders, application accounts that send mail, scan-to-email devices, mobile profiles, MFA rollout timing, DNS cutover windows and the folder structures people have built over a decade all need to be accounted for before the migration night, not during it.
We survey first, build a plan with a rollback position, migrate data in advance where the platform allows it, and schedule cutover outside working hours. Staff receive short, practical instructions covering exactly what changes on their side.
File migrations get special attention. Copying a shared drive into SharePoint without redesigning permissions and structure reproduces years of accumulated mess in a system that behaves differently. We map the structure, agree what moves, what archives and what changes, and set sync up so people can actually find their work afterwards.
Governance and data
Purview, retention and knowing where information lives
Governance sounds like an enterprise concern until a client asks how long you keep their records, a departing employee's OneDrive needs preserving, or someone shares a folder externally without an expiry date. Microsoft Purview provides the tooling for classification, retention, data loss prevention and eDiscovery — and it works best when configured to match a policy the organization has actually decided on.
We help define practical rules: which categories of information matter, how long they are retained, who may share what externally, and what happens to a mailbox and file library when someone leaves.
Backup is a separate and frequently misunderstood question. Microsoft protects its own infrastructure and provides limited recovery windows; it does not guarantee restoration of data your staff deleted months ago or that ransomware reached through a synced device. Independent backup of Exchange Online, SharePoint, OneDrive and Teams data closes that gap.
- Information classification
- Retention and deletion policies
- Litigation hold and eDiscovery support
- Data loss prevention rules
- External sharing expiry
- Departing-employee data handling
- Third-party 365 backup
- Restore testing for mail and files
- Sensitivity labelling where warranted
- Documented governance decisions
Copilot and AI
Microsoft Copilot, once the groundwork is done
Copilot answers questions using the content a user already has permission to see. That is exactly why permissions and file hygiene need review before deployment — otherwise it becomes an efficient way to surface information that was over-shared years ago.
- Copilot licensing guidance
- Permission and over-sharing review
- SharePoint and OneDrive cleanup
- Sensitivity labelling for sensitive content
- Pilot group selection
- Practical use-case coaching
- Prompt and usage guidance for staff
- Acceptable use policy for AI tools
- Audit and monitoring of AI activity
- Measured rollout and review
Licensing and cost
Paying for the Microsoft 365 you actually use
- 01
Plan fit review
Business Basic, Business Standard, Business Premium and the enterprise plans differ in ways that matter — particularly around Intune, Defender and Entra ID features. We map licences to the roles and security requirements in your organization.
- 02
Add-on rationalization
Standalone add-ons frequently duplicate capability already included in a plan you own, or an upgrade replaces three separate purchases at lower total cost.
- 03
Seat reconciliation
Unassigned and stale licences are reviewed regularly. Paying for departed staff for a year is common and entirely avoidable.
- 04
Renewal and term planning
Renewal dates, commitment terms and price changes tracked so decisions are made ahead of time rather than under an auto-renewal deadline.
Questions
Frequently asked questions
- Do we need a backup for Microsoft 365?
- Yes. Microsoft protects the platform's availability, but recovery of deleted or maliciously altered content is limited by retention windows and configuration. Independent backup for Exchange Online, SharePoint, OneDrive and Teams gives you point-in-time restoration long after Microsoft's own recycle bins have emptied.
- Can you move us from an on-premises Exchange server to Microsoft 365?
- Yes. We survey mailboxes, public folders, shared calendars, applications and devices that send mail, plan a cutover window outside working hours, migrate data in advance, and provide staff with short instructions on what changes for them. Rollback positions are defined before the cutover, not improvised during it.
- How much does Microsoft 365 support cost?
- Support is normally included in a managed IT agreement priced per user. Standalone engagements — a security review, a migration, a tenant cleanup — are quoted as projects. Licence costs are separate and paid to Microsoft or through a reseller, and we will tell you plainly when a different plan would cost you less.
- Is our tenant secure if we already have MFA turned on?
- MFA is the most important single control, but it is not the whole picture. Legacy authentication may still be permitted, administrative roles may be over-assigned, mail forwarding rules may go unmonitored, audit retention may be too short, and external sharing may be unrestricted. A configuration review identifies which of those apply to you.
- Can you help us adopt Teams properly rather than just installing it?
- Yes. Most Teams frustration comes from structure, not software: too many teams, unclear channel purpose, files scattered between chat and SharePoint, and no guest access rules. We design the structure, migrate content into the right places and give staff practical guidance.
- Should we move our file server into SharePoint?
- Often yes, but not by copying it as-is. Permission models differ, path lengths and file types matter, and a decade of accumulated folders usually needs pruning. We assess the share, plan the structure, agree what archives and configure sync so staff can work the way they expect.
