Fix Got Alert About Unusual in Microsoft Account on Windows

When Microsoft Account stops working as expected, start with the shortest official checks before you reinstall anything.

Problem Description: Got Alert About Unusual

Hi, I'm having a really weird issue with a Microsoft account belonging to me. I got an alert from Microsoft to one of my personal gmail accounts that there was an unusual sign-in to a Microsoft account of mine from an IP from Brazil but it said that account was "ja*****" with no domain name listed. I have a university e-mail account that's registered to a Microsoft account but when I signed in (after changing the password) it didn't show that sign in attempt in the history. I remembered that years and years ago (I got this e-mail address 19 years ago) I registered this university e-mail account with Microsoft as both a work/university account and a personal account accidentally and I could access both accounts (I confirmed this used to be possible with my university IT dept) but now I can only access the work/university account. I'm worried that someone was able to get into that personal account and I feel like that makes sense considering that 1) the alert said the account was "ja*****" without the domain name and when I use hotmail, gmail, or protonmail accounts it shows the whole domain name so maybe university domains aren't recognized by automated microsoft emails 2) my microsoft university work account doesn't show a recent sign in from an IP in Brazil, and 3) Microsoft verified that my microsoft work account doesn't have the personal gmail account where I got the alert listed as the primary or secondary e-mail address so I wouldn't have gotten an email alert to that email in the first place so I'm thinking the personal account did have that e-mail listed.  I contacted both my university IT dept and microsoft directly but so far no one is able to help. Microsoft couldn't even tell me which account "ja*****" is even referring to because apparently they have limited access on their end. I escalated it to a supervisor at Microsoft and they said my only options were to ask the community hub (and my post seemingly disappeared) or to go to the police to ask them to track the IP. It's kinda freaking me out because I remember using microsoft onenote on the personal account and as an undergrad I could totally see myself putting sensitive information on there. Does anyone know anything about this or have a suggestion where to go from here? Is it even possible to still access my university microsoft personal account? It's a little out there but it really feels like someone is accessing an account that is difficult but not impossible to access after system changes and might have access to sensitive personal data without me being able to verify it. Thanks!

Likely Causes Behind Suspicious Login Issues Root Factors

2. Monitor for unusual sign-in attempts and note details like IP addresses to report to Microsoft.

Alternative Solutions for Secondary Security Fixes

1. Retry the Microsoft-side steps after restarting the app and device.

2. Test the same action in a private browser session or a new blank file to isolate account vs file issues.

3. Capture exact error text and screenshots before contacting Microsoft Support or your administrator.

Working with WPS Office: WPS as a Local Alternative

WPS Office cannot replace Microsoft account, activation, or cloud fixes for this scenario. It remains one of the best free Microsoft Office-compatible alternatives for opening and editing local files.

1. Download and install WPS Office from the official website.

2. Open local Word, Excel, PowerPoint, or PDF files in the matching WPS app.

3. Save a working copy locally while Microsoft-side issues are resolved.

4. Return to Microsoft Office after the primary fix succeeds.

If you need a practical local workspace in the meantime, try WPS Office.
