After years of deployments, migrations, and “optimizations” of Unified Communications and Collaboration tools, one thing is clear: the most common problems are no longer technical.
They are basic mistakes we keep repeating, even with mature platforms like Microsoft Teams, Zoom, or Google Meet.
Here are three that I still see every day and that, honestly, should not be happening in 2026.
❌ Error 1: Assuming all users use Unified Communications and Collaboration tools the same way
One of the most common mistakes is treating collaboration as a single, uniform experience for everyone.
In reality:
- An administrative user, an executive, a support agent, a meeting room user
They do not use collaboration tools the same way, nor do they have the same needs.
And yet, organizations continue to apply:
- The same policies, the same restrictions, the same expectations
The result
- User frustration
- Workarounds
- Shadow IT
- Unnecessary support tickets
Basic best practice
Design Unified Communications and Collaboration by scenarios, not by platform:
- Individual work,
- Internal collaboration
- External communication
- Meeting rooms
- Voice and critical calling
If everything is the same for everyone, something is poorly designed.
❌ Error 2: Copying configurations without understanding the context
“I saw it configured this way in another tenant.”
“That’s how it came in the guide.”
“That’s how we left it in the previous project.”
This one is a classic.
Many collaboration configurations are inherited:
- From past projects, from other customers, from generic recommendations
Without stopping to ask:
- Is this environment actually the same?
- Does this organization have the same risk profile?
- Does this use case really apply here?
The result
- Policies no one understands
- Features blocked “just because”
- Admins fixing problems they created themselves
Basic best practice
Every policy should be able to answer a single question:
Why is it configured this way?
If you cannot explain it in one sentence, it probably should not be configured that way.
❌ Error 3: Not defining clear ownership of Unified Communications and Collaboration tools (beyond IT)
Collaboration platforms usually live in IT…but they directly impact:
- Security,
- Legal
- Facilities
- Human Resources
- The business
Still, many decisions are made:
- In isolation
- Without validation
- Without alignment
The result
- Conflicts when incidents happen
- Reactive changes
- Blurred responsibilities
When something breaks, the question always appears:
“Who approved this?”
And very often, the answer is not clear.
Basic best practice
Unified Communications and Collaboration need clear owners, not just administrators:
- Who defines what gets recorded
- Who authorizes external access
- Who decides how meeting rooms are used
- Who validates legal or privacy impact
Collaboration tools stopped being “just calling platforms” a long time ago.
The key point
In 2026, the biggest problems with Unified Communications and Collaboration tools:
❌ Do not come from the technology
❌ Do not come from the cloud
✅ They come from poorly thought‑out or undocumented decisions
The platforms are already good enough.
What still fails is how we use them and how we govern them.
Which of these mistakes do you still see in your environment? Or which one would you add to the list?
