Hello there,
Do you know if any MS Teams administrators can assist me with this issue?
I'm not an admin myself; I'm just an end user in a big company. Some time back I set up Teams on my personal PC using my work account. I'm unsure if a special exception was applied for this device. If I try to log in from another PC or even install Windows on the same machine, I receive an error stating that this device isn't managed and I can't access it.

I suspect that possibly an admin once whitelisted my personal PC for a one-time use. Without any intention of being malicious, could I try to mimic the whitelisted PC on another computer if needed in the future? I'm also worried about whether our system admin might have made an exception again, especially if this happened before.

Is it that easy to spoof the MAC address of the whitelisted machine, or is there more to it?
Thanks for your help with this. It's just a curiosity and could cause future problems.
Best regards,

There are various approaches, depending on your network setup.
This is essentially a task for your IT administrators.

Just to note, spoofing the MAC address didn't help
