Why are Microsoft Data Centres logging in to my Office 365 accounts? Activity Alerts - BAV2ROPC
Hello, I have an activity alert set up to email me whenever a log in is detected from one of my 12 office 365 email users. These emails contain the username logging in and the IP address the log in originated from. Until the end of 2019, all IP addresses were expected, either being that of the office, the Vodafone mobile network or the home addresses of the sales guys. In 2020, I have started getting log in alerts, which according to https://whatismyipaddress.com/ are from Microsoft Datacentres in Ireland, Holland and Austria, all with "Microsoft Corporation" as the ISP and sometimes with the same for the Organisation and sometimes with "Microsoft Azure". e.g 40.101.88.221 (Amsterdam), 40.101.102.149 (Dublin). Worried about potential breaches, I contacted Microsoft Support (who by the way are always ON IT, thank you) who helped me find info in the audit log to say the User Agent is BAV2ROPC, which lead me to this page https://www.reddit.com/r/Office365/comments/bl90gw/bav2ropc_user_agent_in_logs/ where someone's found it means "Business Apps v2 Resource Owner Password Credential", which is apparently the User Agent for an updated version of Outlook Mobile. I have a couple of questions / observations and wondered if anyone could shed any light on this. 1) My users don't know their passwords so it's highly unlikely they've been phished, so I don't think these are breaches. 2) My email account has triggered log ins from Microsoft IP addresses, and I have 2 factor authentication turned on where I received a text message code to my mobile. I have not received texts in relation to these logins, so again I don't think it's a breach. 3) I don't use Microsoft Outlook on my mobile, so don't think I'd be generating this BAV2ROPC user agent (but I am on the Activity Alerts). 4) If it was a device I was using causing this user agent, why aren't the Activity Alerts logging my IP address from my device's location? 5) My account is used to sign in programatically in a piece of software I wrote, so that could explain it for my account, but I'm also getting alerts for users who only access their email on their android phone on the built in email app. 6) The frequency I'm receiving Activity Alerts from Microsoft IP addresses is increasing. I get a few a day now. In summary, I don't think there's anything untoward goin on, but as a responsible admin, I'ld like to understand exactly what's occuring. Many thanks, Dave
Hacked Microsoft Account Recovery with Semi Access
I'm at a complete loss and it is infuriatingly ridiculous. I am entirely unable to get a hold of a human being at Microsoft and am being turned down by automated responses nonstop. So here's what's happening: My Microsoft account has been hijacked (obviously not this one) for its valuable Minecraft account and has now been sold. I am logged into my account via my PC, have full access of the main email address, but I have been locked out of my account using the alias email. Whenever I want to log in to my account, it wants to instead send a code to an email address I do not own and can't access. I have tried the Sign-In Helper, the Recovery Form, the hotline, the support email without any result, let alone a non-automated response. I sadly don't have the Recovery Code of my 15 year old-ish account. Since I still have full access of my email address I get updates of security info being changed and what not. Last month a stranger sent me screenshots of someone trying to sell my Minecraft account, for which I myself have received multiple buying offers, and voila yesterday I received notification of my alias mail address changing followed by Minecraft server apps being added to my Microsoft account. While I had already given up retrieving my account, whenever I get notifications my heart sinks a new while some hope sparks up again. Do you people have any idea of what I could do? I don't even rule out legal actions at this point. While I do of course have the email address of the hijacker and the buyer, I fear that contacting them results in me being locked out permanently. I'm just begging to catch the attention of anyone involved with Microsoft. This being walled out with automated responses is killing me.
