FYI: Here's what I'm seeing:

yes, you are correct... resolved at my local dns:

master:~$ host outlook.office365.com
outlook.office365.com is an alias for

outlook.office365.com.glbdns.microsoft.com is an alias for

outlook-latam.office365.com has IPv6 address 2a01:111:f400:2c00::6

outlook-latam.office365.com has IPv6 address 2a01:111:f400:1800::6

2a01:111:f400:c00::6 and 2a01:111:f400:1800::6 are not responding to
queries on port 443, the other two (2a01:111:f400:2c00::6 and
2a01:111:f400:800::6) are working...


MS should fix this...

Quite Interesting...

from Europe, using ipv6, it seems to be working:
---
<Zarko.Kecic () rnids rs>master:~$  telnet -6 outlook.office365.com 443

Trying 2a01:111:f400:800::6...
Connected to ipv6.exchangelabs.com.
Escape character is '^]'.

The IP address you have mentioned is working fine.

[root@stingray ~]# telnet 2a01:111:f400:800::6 443

Trying 2a01:111:f400:800::6...
Connected to 2a01:111:f400:800::6.

Escape character is '^]'.

but outlook.office365.com is not resolving to the above address google n
he dns.
