Microsoft365 & AirVPN heads up

Recommended Posts

So i have created an Office365 test tenant as to do some lab work and i notice some strange behaviour.

While connected to the AirVPN i can login to the portal and everything works seamlessly however i cant sent or receive emails from the tenant.

the emails are bouncing back with error:

Remote Server returned '550 5.7.501 Service unavailable. Spam abuse detected from IP range. For more information please go to http://go.microsoft.com/fwlink/?LinkId=526653.  

So if i disconnect from AirVPN, i can actually sent and receive emails fine from O365. The issue was on Beteljuice in the UK however it seems to happen on other servers too.
I had to call Microsoft to whitelist the exit ip address for my tenant. So make a note that AirVPN's exit ip is flagging up on MSFT datacenters.

Just a heads up boys and girls.

All VPN IP addresses are blacklisted on Microsoft. This has been a problem around here and other VPN providers for years. :) If you unblock them, chances are one bad apple will spoil the barrel again some time later. As we Germans like to say, it's a battle against windmills (meaning, it's hopeless).

» If you're new, take some time to read LZ1's New User Guide to AirVPN. On questions, use the search function first. On errors, search for the error message instead.

» If you choose to create a new thread, keep in mind that we don't know your setup. Give info about it. Never forget the OpenVPN logs or, for Eddie, the support file (Logs > lifebelt icon).

» The community kindly asks you to not set up Tor exit relays when connected to AirVPN. Their IP addresses are subject to restrictions and these are relayed to all users of the affected servers.


» Furthermore, I propose that your paranoia is to be destroyed. If you overdo privacy, chances are you will be unique amond the mass again.
