Hello everyone and welcome to another episode of Microsoft Knowledge Nuggets here on M365.
FM, I'm your host, Mirko Peters.
Today's topic is one that almost everyone has heard of, but few people can actually explain.
Microsoft Mesh, you've heard the buzzwords,
metaverse, mixed reality, 3D meetings.
But right now, what does Mesh actually do for you?
Here's the short answer.
It's a way to meet in 3D virtual spaces inside Microsoft Teams.
Imagine stepping into a room where you and your colleagues show up as avatars.
You can walk around, chat on the side,
and still watch presentations together.
It's not a game and it's not a toy.
It's just a different way to hold a meeting.
Now the tricky part, Mesh has gone through a major change.
That standalone metaverse platform Microsoft originally announced, retired.
What's left is a feature built right into Teams,
simpler, more practical, and actually available to you today.
By the end of this episode, you'll understand what Mesh is,
how it works, why Microsoft changed course,
and whether it's worth your time, grab your coffee, and let's dive in.
So what exactly is Microsoft Mesh?
Let's start with a simple definition.
Microsoft Mesh is a platform for shared 3D experiences.
Not a game, not a VR toy.
It's a collaboration tool that adds a sense of physical presence to remote meetings.
Compared to a regular video call,
on a normal Teams call you see faces in little boxes.
Everyone stares at the same grid.
There's no sense of where anyone is in relation to you.
In Mesh you see avatars sitting in a virtual room together.
You can look around, you can move closer to someone.
And here's the interesting part.
They have voice changes depending on how far away they are.
That's the core promise of Mesh.
It makes remote interaction feel more natural.
Your brain picks up on spatial cues.
You know someone is over there or next to you.
That sounds small, but it actually helps with engagement and memory.
When you feel like you're in a room with people,
you pay attention differently.
Now let me clear up a common confusion.
Mesh is not a virtual world you live in.
It's a meeting space you enter for specific sessions.
No persistent universe, no digital real estate to buy,
no avatar walking around when you're not in a meeting.
It's a room, not a planet.
You join, you meet, you leave.
The technology runs on your PC, Mac or VR headset.
It supports MetaQuest headsets today,
and Apple Vision Pro support has been announced.
But here's the key point.
You don't need special hardware for basic use.
Just a webcam and the Teams app, that's it.
But Mesh wasn't always as simple.
Let's talk about the big pivot Microsoft made.
And why it actually helped users like us.
The big pivot from Metaverse platform to Teams feature.
Back in 2021, Microsoft announced Mesh
as this grand Metaverse platform,
CEO Satyanadella called it the next frontier.
They talked about standalone apps,
custom worlds built with the Unity game engine,
HoloLens support, and events for up to 330 people.
It was a huge vision.
But by 2024, Microsoft started rolling Mesh
features into Teams instead of keeping it separate.
By December 2025, the standalone platform was officially
retired.
The Mesh Toolkit, which let developers build custom 3D worlds,
shut down in June 2025.
The dedicated Mesh app for PC and MetaQuest?
Gone, the Mesh Cloud.Microsoft website also gone.
What happened?
The reason is actually pretty simple.
Companies didn't want another platform to manage,
since they already have Teams and Microsoft 365.
They didn't want to learn a whole new tool just
for a 3D meeting.
What they wanted was 3D collaboration inside the tools
they already use.
So Microsoft listened.
The result is what we have today.
Immersive spaces in Teams.
It's a lighter, more accessible version of what
Mesh was supposed to be.
Think of it like this.
Imagine someone building a brand new office building
from scratch, then deciding to just add a nice conference room
to the building where everyone already works.
No separate building, no separate keycard, just one space
that works with everything else.
Now, there is a trade-off.
With immersive spaces, you get fewer features.
Meetings are limited to 16 people.
No custom worlds.
You can build yourself.
And HoloLens support ends in 2027.
But here's the thing is, it's far easier
to adopt for most organizations that trade off is worth it.
The goal isn't to create a virtual reality universe.
The goal is to make your meetings more engaging and collaborative.
You don't need a developer.
You don't need a 3D artist.
You just need a Teams meeting.
So what does this mean for you?
Let me show you exactly how to use it.
How to join an immersive space in Teams.
Here's the best part.
You don't need to learn a new tool or install a separate app.
You just need a regular Teams meeting.
First, schedule a Teams meeting like you normally would.
Nothing special, just a normal calendar invite.
Once you join the meeting, you'll
see the familiar Teams interface with your camera feed,
the chat panel, and the participant list.
Now look at the top of the screen and click the View button.
You'll see an option that says immersive space 3D.
Click it, and that's it.
You're in.
The first time you do this, Teams will ask you to pick an avatar.
If you haven't set one up yet, the app
will guide you through choosing a face shape, hairstyle,
and clothing.
It takes about two minutes.
Then you'll pick a space environment.
Microsoft gives you several options,
an outdoor gathering space with mountains in the background,
a Zen conference room with a calm atmosphere,
or a classic boardroom setup.
Pick whichever feels right for your meeting.
The environment you choose sets the tone.
So think about what kind of atmosphere you want.
Now you're inside the immersive space.
You see yourself as an avatar.
You see your colleagues as avatars, and you can move around.
The controls work like this.
If you're on a PC, use the WASD keys to walk forward,
left, back, and right.
Left click and drag to look around the room.
Press E to rotate, left, Q to rotate, right.
Hold Shift to run.
If you want to get somewhere fast, just click on any seat,
and you'll teleport there instantly.
It feels a lot like a video game,
but don't let that intimidate you.
The controls are simple, and you'll
get the hang of them in about 30 seconds.
Once you get used to moving around in 3D,
you'll find it feels more natural than a flat grid of faces.
Down at the bottom of the screen,
you'll see your control panel.
There are reaction buttons, so you can clap, smile,
give a thumbs up, or send a heart.
There's an environment settings button
to switch to a different space theme, mid-meeting.
There's a sitting overview that shows who's sitting where.
And you can change your avatar on the fly
if you want to switch outfits or appearance.
Here's something important about privacy.
When you join an immersive space, your camera stays
off, your peers in avatar, so nobody sees your actual face
or your messy background.
Audio still works through your microphone and speakers,
so you can talk normally.
If some people on the call don't join the immersive space,
they'll still see your avatar on their screen.
They just won't be in the 3D room with you.
Think of it as walking into a specially designed meeting room
in your office building, where the walls are digital,
but the experience of being together in a shared space
is what matters.
This setup is perfect for remote teams
who want a stronger sense of presence
without worrying about how their home office looks.
Now let's talk about the killer feature
that makes Mesh feel real.
Spatial audio.
Spatial audio, the secret source.
Think about how you hear someone in a real room.
If they're standing next to you, their voice is loud and clear.
If they're across the room, it's quieter.
If they're behind you, the sound comes from behind.
Your brain uses these cues to figure out
where people are and who's talking.
Mesh does the same thing.
It's called spatial audio, and honestly,
it's what makes the whole experience feel real.
Walk away from the group in your virtual space.
Their voice is fade, walk closer, and they get louder.
Turn your avatar to face someone,
and their voice shifts to the direction you're looking.
Simple idea, but it completely changes how a meeting feels.
Side conversations become possible again.
In a regular Teams call, if two people want to chat privately,
they have to send a separate message
or leave the meeting entirely.
In an immersive space, they just step aside.
Their avatars move a few feet away from the group
and their audio moves with them.
The main group doesn't hear them,
and they don't hear the main session.
Quick chat then walk back and rejoin
that's something you just can't do on a standard video call.
This solves a real problem in hybrid work.
Remember the last time you were in an actual office?
You could tap a colleague on the shoulder,
pull someone aside for a quick word without interrupting everyone.
Those moments are nearly gone on regular video calls.
Spatial audio brings them back.
It also cuts down on meeting fatigue.
On a normal video call, you're locked into one speaker at a time.
Everyone stares at whoever's talking.
Exoresting.
In an immersive space, natural social dynamics kick in.
You look at who's talking, you turn to follow a speaker,
you feel the room, your brain does what it evolved to do,
and that makes the meeting way less tiring.
You don't need a VR headset for this,
a simple laptop with speakers works,
but to really feel part of the space,
you need an avatar that represents you.
Avatars.
Your digital self.
Your avatar is your body in the mesh world.
It's how other people see you.
And it's surprisingly expressive.
The avatar mimics your head movements,
turn your head in real life,
and the avatar turns its head.
If you have a webcam, it might even smile when you smile.
Not perfect.
It won't catch every micro expression.
But it's enough to make the interaction feel human.
You customize your avatar in the Teams avatar app.
Find it in the Teams app store,
or through the immersive space setup.
Pick your face shape, hairstyle, skin tone, clothing, accessories.
You can go realistic or something more stylized.
It doesn't need to be photorealistic.
Think of it as a more expressive version of your profile picture,
something that feels like you without being an exact copy.
During a meeting, you can change your avatar instantly,
swap from casual clothes to a suit for a presentation,
or switch to a different look for a team social event.
You can do it on the fly without leaving the meeting.
Why does the avatar matter?
Because it creates psychological presence.
Having a body in a virtual space improves attention and recall.
When you see yourself sitting in a room with other people,
your brain treats the experience differently.
You're less likely to multitask.
You're more likely to remember what was said.
You feel like you're actually there.
So you're in an immersive space with avatars and spatial audio,
great for a team meeting.
But Mesh can do more,
especially when organizations build custom environments.
Custom environments, the developer angle.
Before Microsoft retired it, Mesh had a whole different side to it.
Organizations could build their own 3D worlds
using something called the Mesh Toolkit for Unity.
And some companies went all in.
Take Accenture, they built a virtual campus called One Accenture Park
and used it to onboard over 300,000 new hires.
New employees could explore virtual campus areas,
attend orientation sessions and network with colleagues,
or without leaving their homes.
Those custom worlds were rich.
Product showcases where you could walk around a 3D model of a new car,
training simulations for medical procedures or safety drills.
Branded showrooms for sales events,
they looked impressive and they served real business purposes.
But they came with a cost to build them.
You needed Unity developers.
You needed 3D artists.
You needed IT support to manage the deployment.
It was a serious investment.
That capability is now gone.
The Mesh Toolkit officially retired in June 2025.
No new custom worlds can be built,
existing ones still work, but they won't get updates.
If you were hoping to create a branded experience for a sales event
or a training module, you're out of luck with the current version.
What remains are the default environments Microsoft provides.
You get a handful of pre-built spaces.
The outdoor gathering, the Zen conference room, the boardroom,
you can switch between them during a meeting with one click,
but you can't create your own.
That's a significant limitation for organizations
that wanted something unique.
Now, Microsoft has hinted at AI-powered environment generation
in the future.
The idea is that you might describe what you want
and an AI builds the space for you.
That's not here yet, but it's something to watch for.
So who is actually using Mesh right now?
Let's look at some real use cases.
Real use cases when Mesh shines.
Let's start with Accenture because they're the biggest example.
They onboarded over 300,000 new hires in one Accenture Park.
That's not a small pilot program.
That's a massive real world deployment.
New employees could walk through virtual campus areas,
attend orientation talks and network with colleagues, all in 3D.
And they did it at scale, then there's team building.
Remote teams are using immersive spaces for informal gatherings.
Virtual happy hours, holiday parties, brainstorming sessions.
The spatial audio makes these feel less artificial
than a standard video call.
You can split off into smaller groups naturally.
You can walk over to someone and start a conversation.
It's closer to what happens in a real office break room.
Product showcases are another strong use case.
Imagine an automotive company that wants to show a new car model.
Instead of showing slides, they build a 3D environment
where attendees can walk around the car.
Look at the interior, see the details,
ask questions while standing next to the virtual vehicle.
That kind of experience is much more engaging than a PowerPoint deck.
Training and education is where mesh really shines.
Medical simulations where multiple trainees
are in the same 3D scenario,
safety drills for manufacturing environments,
soft skills practice for customer service teams.
The key is that everyone is in the same space,
interacting naturally.
You're not watching a video.
You're participating.
Here's the insight that ties all of these together.
The most successful use cases involve interaction,
not passive watching.
Mesh works best when people need to move, talk and collaborate.
If you're just going to stare at slides,
a regular team's call does the job.
But if you need people to explore,
discuss and work together in a spatial context,
mesh adds real value.
So with all these capabilities and the pivot to teams,
what's the verdict for you?
The verdict should you care.
Let's be honest, mesh isn't for everyone.
If you only do one-on-one calls or large webinars,
you won't miss it.
The regular team's experience handles those situations just fine.
But for team collaboration and group dynamics,
for that feeling of being together when you're not,
that's where mesh earns its keep.
Now, the limitations are real.
You're capped at 16 people per immersive space.
And there are no custom environments.
You also need decent hardware.
This won't run smoothly on that five-year-old laptop,
your IT department hasn't replaced yet.
It's still an early adoption among Microsoft 365 users,
so don't expect every meeting to be in 3D.
And most people haven't tried it.
So who benefits most?
Remote teams that struggle with connection and engagement,
hybrid teams that want to recreate
those informal water cooler moments
that just don't happen on video calls and trainers
and facilitators who need spatial context,
where someone is in relation to something matters.
If that sounds like your team, mesh is worth a look.
Here's what's coming.
Microsoft is investing in AI-driven features like AI guides,
chatbots that can be anchored to specific locations in a space,
walk up to a virtual exhibit and an AI assistant
explains what you're looking at.
They're also expanding VR headsets support to Apple Vision Pro
and the platform will get richer, not cut back.
My advice?
Try it yourself and don't overthink it.
Schedule a short test meeting with a colleague
and see if the spatial audio and avatar presence
makes a difference.
It's just another view option in Teams.
And if it doesn't work for you,
you're back in a normal meeting in one click.
No harm done.
Let's wrap this up.
So here's the knowledge nugget.
Microsoft Mesh is not a mysterious metaverse.
It's a simple way to bring your team together
in a 3D space right from Teams,
the pivot from standalone platform
to integrated feature made it more accessible,
if less ambitious.
You can try it today with no extra cost or setup.
Step into a virtual room, move around
and have real-side conversations.
It might change how you feel about remote meetings.
