And that has indeed been the case. Various users have voiced their concern that they are getting an Unusual Activity Detected prompt in their Microsoft Outlook account. The IP Address being shown is not their own, but rather, it’s from the Microsoft Data Center. In a more technical term, the IPv4 address ranges from 13.101.0.0-13.101.255.255, with 13.101.120.212 being the most prominent one and the Protocol being IMAP/POP3 in most cases. So this begs the all-important question- is there a fix? Let’s check it out.
Fix MS Outlook Unusual Activity Detected from Microsoft IP Address
Well, this is a server-side issue, and as of now, there’s no way of stopping these prompts. However, we would still recommend you enable Two-Factor Authentication/Two-Step Verification on your Microsoft Outlook. For the unaware, doing so will add an additional layer of security to your account. So after entering your account password, you will also have to provide an additional security code, depending on the method you chose during the setup. Without any further ado, let’s get started. That’s it. It’s the best you could do when it comes to fixing the Unusual Activity Detected issue in Microsoft Outlook. Even though the IP addresses were from the Microsoft Data Center but there have been a few cases wherein people with malicious intent mask the IP address of a secure location to grant access to the system. Therefore, enabling 2FA or 2SV is the best way forward in the current scenario.
As far as the official stance on this matter is concerned, the developers are aware of this issue, but they haven’t given out any ETA for the rollout of a fix. As and when that happens, we will update this guide accordingly. In the meantime, the aforementioned workarounds are your best bet.
