Onboarding a new IT provider should make life easier, not bring business to a halt.

But shortly after a new client began transitioning to CatchMark Technologies, something alarming happened.

Email stopped working. Employees couldn’t send messages. They couldn’t receive messages. For any business, an email outage can quickly bring operations to a standstill, so our team immediately began investigating.

The Symptoms

The initial reports seemed straightforward:

• A new client experienced a complete email outage during onboarding.
• Users were unable to send or receive email in their production environment.

At first glance, this could have been anything, from Microsoft’s cloud services to DNS issues or mailbox corruption.

The challenge was determining where to start.

Following the Evidence

Rather than jumping to conclusions, our team followed the troubleshooting process.

Because the client was still in the middle of onboarding, the first step was verifying Microsoft 365 licensing.

We reviewed:

• Current Microsoft licensing
• Account status
• The licensing history between the previous IT provider and the new Microsoft 365 environment

That’s when we found the real problem.

The Root Cause

The issue wasn’t Microsoft. It wasn’t Exchange Online. It wasn’t a network outage.

The previous IT provider had cancelled the organization’s Microsoft licenses before the transition had been completed, and before authorization had been given to do so.

Without active licenses, users immediately lost access to their email services.

The Resolution

Once the cause was identified, the fix was straightforward.

Our team:

• Provisioned the client with the correct Microsoft licenses
• Applied and activated licensing for the affected users
• Verified mailbox functionality
• Restored email service so employees could send and receive messages again

Business operations were back to normal shortly after the licenses were reapplied.

The Business Takeaway

Technology problems aren’t always caused by broken technology. Sometimes the issue is process.

Transitions between IT providers involve dozens of moving pieces. If licensing, permissions, or service ownership change too early, it can create unexpected downtime that affects the entire organization.

That’s why careful planning, clear communication, and verification at every step matter.

At CatchMark Technologies, we don’t just fix the symptoms, we work to uncover the real cause so the problem is resolved correctly the first time.
