Can you go to www.outlook.com on the computer (not phone), and go to the gear icon on the upper right to pull up the Settings page, then use this screenshot to guide you to change the language?

“My Outlook.com/Hotmail account is stuck in Vietnamese on the web interface, even after clearing browser cache, using private/incognito windows, and trying the direct English URL. The iPhone app is fine.”

2026-03-06T18:36:38.78+00:00 You are welcome.
I do want you to go through this list of items though. Seeing a lot of this type of issue lately in the forum, and often due to account being compromised.. rather safe than sorry.
Please complete these steps on a computer, not on a smartphone or tablet.
====================
First, go to https://www.outlook.com and sign in.
Click the gear icon in the top right corner to open Settings.
Under Mail, review the following areas:
Rules
If any rules are listed, delete all of them.
Conditional formatting
If anything is set up there, delete it.
Forwarding and IMAP
If you see any entries or settings you did not create, remove them. Turn off POP and IMAP.
Junk
Review Safe sender and blocked list. If you don't recognize any, remove them.
After that, exit Settings and return to outlook.com.
Open the To Do section by clicking the blue checkmark icon on the left side. Delete anything there that was not created by you.
====================
Go to https://account.live.com.
Under Your info > Sign-in preferences, review all aliases on the account. If you see any alias you do not recognize, remove it.
Next, go to the Devices section of your Microsoft account and remove any devices you do not recognize.
====================
Please also do the following in Security section
Change your password
Enable two-step verification
====================
Then go to Security > Manage how I sign in and make sure all contact information belongs to you.
On that same page, scroll down to App passwords and remove any existing app passwords.
Also on the same page, click on Sign out everywhere. This is intended to disconnect any active sessions that may still be connected. Please note that this can take up to 24 hours to fully take effect.
