If i am in country A, i should be working in country B but I have VPN on my phone and use teams on my phone - will the admins/company see my status or be alerted?
Thanks in advance!
Your admins would see the IP address of your VPN when you login to Teams. Since VPNs share a lot of IPs between all users, its very possible the admin would receive an alert due to your suspicious login coming from untrustworthy IP addresses.
Depends on the setup (MDM, company apps, etc). I would defer to assuming yes.
yes they can see the IP of the VPN and block it if they want based on conditional access. Our cyber teams is getting me to set up policies at the moment to block exactly this from happening. e.g if you are connecting to our companies Teams from a Chinese IP address it will block your request.
Depending on the vpn config it could also be split tunneling teams traffic 
There are ways other than IP your admins can use to determine the location of your computer if they want to and have appropriate software.
It depends on how serious the org is about enforcing this policy.
To those who answered that the IP may be detected, or flagged: what about a VPN that can report a different country?
I use this feature often when participating in meetings “in other countries” when communication is limited to “locals” only. I select the country I want “to connect from” and it was never an issue.
How would something like that work for the OP?
One of our new users was having trouble logging into our network, while on site.
They were using a personal vpn, and the endpoint was blocked on our network due to “suspicious traffic”. They had to turn off their “personal vpn which protects them from the horde” before they could log into our vpn.
So yes this kind of thing does happen.
So if i am already taking a holiday in country A with teams on phone and pretends i am back to country B with VPN but actually am still in country A, its not gonna work right
well, guess my holiday plan won’t work. Thank you for letting me know though
It will work usually but it will show that you’re at different location than you normally are in country B because you’re using a shared VPN IP that also may be flagged as suspicious or untrustworthy.
The system will alert admins of any sign ins that came from different locations that the user normally signs in from, even in the same country.
If it doesn’t work, you just won’t be able to sign in. Your sign in will be blocked.
It could also be flagged as suspicious travel, especially if you’ve already logged in from Country A and then switch to country B. The system will detect It is impossible to travel that fast between countries and may alert the admin to something suspicious.
yep its likely the system will put an alert on your account as suspicious login activity. Depending on the company policies will dictate what happens, auto blocking your account, denying the login request, alert admins, nothing.
I see, it makes sense. Thank you
