How to Configure Microsoft 365 for a Construction Company with 20–100 Employees

Construction office team using Microsoft 365 for collaboration

Microsoft 365 is the backbone of most construction IT environments, but default settings aren’t secure enough for jobsite operations.

  • Email compromise
  • File-sharing errors
  • Lost project data
  • Insurance non-compliance

Improper configuration can result in:

Here’s how to configure Microsoft 365 correctly.

1. Enforce MFA Across All Accounts

Required for:

  • Outlook
  • SharePoint
  • Teams
  • Admin accounts

MFA should not be optional.

MFA is now a baseline insurance requirement. Construction companies reviewing Microsoft 365 security should understand the full scope of cyber insurance requirements for construction companies.

2. Structure SharePoint for Project-Based Access

Avoid dumping files into one shared folder.

Instead:

  • Create project-based libraries
  • Restrict access by role
  • Use expiration rules for external sharing

3. Enable Advanced Email Protection

Use:

  • Anti-phishing policies
  • DMARC/SPF/DKIM
  • Attachment sandboxing

Construction companies are prime invoice fraud targets.

4. Implement Conditional Access Policies

Restrict:

  • Foreign logins
  • Risky IP addresses
  • Non-compliant devices

5. Manage Devices with Endpoint Control

Require:

  • Encryption
  • Compliance checks
  • Remote wipe capability

Poor device management often leads to preventable outages. Contractors should also understand what acceptable IT response times for active construction jobsites should look like when issues occur.

Real Example

A GC with 61 employees reduced phishing incidents by over 70% after enabling advanced email protection and conditional access.

Final Takeaway

Microsoft 365 must be configured for a mobile, multi-location workforce, not a static office.
