MS Outlook users getting 'Unusual account sign-in activity' alerts from Microsoft IP addresses, issue acknowledged
Microsoft’s Outlook is one of the most comprehensive solutions if you are looking for a personal information manager and email client. With millions of users worldwide, it is available as part of the Microsoft Office Suite.
Many said they tried logging out of all devices and signing in to just one device but the problem persists. It looks like enabling two factor authentication isn’t helping either.
I don’t know if I got hacked or not and need help in deciding. Since 2 days or so some IP is logging into my outlook profile. It is just since recently and I am using the account for a while now. My outlook account is connected with Thunderbird locally on my system. IP: 220.127.116.11 is from Redmont, Microsoft datacenter. But I live in Germany and don’t use any IP changing software.
My outlook account notices some unusual IMAP Login from Microsoft at Redmond. I’m noticed from Microsoft Account Service that my outlook account has been exposed some IMAP Logins from each of the IPv4 addresses at 18.104.22.168-22.214.171.124 since 2022-07-11 JST informed as “unusual activity”. And I found with using whois service that these IP may be managed by Microsoft and placed at Redmond city in US.
Allegedly, Microsoft seems to be aware of the issue where Outlook users are getting unusual activity alerts and said they are working to fix the problem.
They also said that there is no need to change password as affected accounts as secure.
Finally got to talk to someone at MS- this was their reply: Thank you for the information. Please be advise that Microsoft is aware of this known issue already. This started to happen even last week and we are already working with this matter.
We even have created a ticket number for this issue while it is still happening.The ticket number for the emerging issue is INC31680156. So they are on it, but no idea when it will be fixed. [EDIT] They also confirmed that the account was secure, no need to change passwords, etc
We hope Outlooks developers soon find out the root cause of the problem and fix it in the coming days.
As always, we will keep track of further developments on the matter and let you know as and when we stumble across more information so stay tuned.
