What this service covers

Migration

Move from on-premises Exchange, Google Workspace, or another provider to Microsoft 365 with zero data loss and minimal disruption.

Setup & configuration

Initial tenant setup, domain verification, user provisioning, security baselines, and conditional access policies configured correctly from day one.

Licensing

Guidance on which Microsoft 365 plans fit your team size and needs — and ongoing license management so you only pay for what you use.

Ongoing management

Day-to-day administration, user onboarding and offboarding, policy updates, and proactive monitoring of your tenant health.

​
Apps and workloads supported

DiekerIT covers the full Microsoft 365 suite. Below are the workloads most commonly optimized for business customers.
Teams channel structure, meeting policies, guest access, calling plans, and integration with SharePoint and OneDrive. You get a setup that matches how your team actually communicates — not a default configuration that creates noise.
Document libraries, site architecture, permission models, and external sharing policies. Avoid the common pitfalls of overly open sharing or overly restrictive access that blocks collaboration.
Mailbox migration, shared mailboxes, distribution lists, mail flow rules, anti-spam configuration, and DKIM/DMARC/SPF setup to protect your sender reputation.
Identity management, single sign-on (SSO), multi-factor authentication (MFA), conditional access, and group-based access control across all your Microsoft 365 services.
Mobile Device Management (MDM) and Mobile Application Management (MAM) through Microsoft Intune — enforce security policies on company and personal devices without disrupting users.

​
How a migration works

Whether you’re moving from Google Workspace, an on-premises Exchange server, or a legacy hosting provider, the process follows a structured path to keep your team productive throughout.
1

Discovery and planning

Audit your current environment — mailboxes, shared drives, calendar data, distribution groups, and any third-party integrations. A migration plan is created with timelines, risk notes, and rollback steps.
2

Tenant provisioning

Set up your Microsoft 365 tenant with the correct domain, security defaults, and initial policies before any data moves. This avoids reconfiguring a live environment.
3

Pilot migration

Migrate a small group of users first to validate the process, catch edge cases, and confirm mail flow, calendar sync, and file access all work as expected.
4

Full migration

Roll out the migration to all users in batches. Cutover is scheduled for low-traffic periods to minimize impact.
5

Post-migration support

Hands-on support in the days after cutover to resolve any issues quickly. Documentation of the final configuration is provided for your records.

​
Tips and optimization

Even if your Microsoft 365 tenant has been running for years, a configuration review often uncovers security gaps, unused licenses, and productivity improvements. Ask about an M365 health check.
Many businesses use only a fraction of what their Microsoft 365 subscription includes. Common quick wins include:
  • Enabling Microsoft Defender for Office 365 safe links and safe attachments if not already active
  • Setting up retention policies to meet compliance requirements without manual archiving
  • Configuring Teams phone to replace a traditional phone system and reduce costs
  • Using Power Automate to automate repetitive approval and notification workflows
  • Activating Microsoft Copilot features on eligible licenses to accelerate everyday tasks
