all my emails wont load

Change Outlook back to English from Settings (gear icon) → General → Language and time, select English under Language (Country/Region), and then select Save. ^1^

Change the language

Using a computer is easiest if the current language is unreadable:

1. Sign in to Outlook.com.
2. Select the ⚙️ gear icon in the upper-right corner.
3. Select General in the left column.
4. Select Language and time—normally near the top under General.
5. Open the first language drop-down and select English (United States) or your preferred English region.
6. Select Save, then refresh the page.

If you use classic Outlook for Windows instead, select File → Options → Language, then add or select English under Office display language. ^1^

Get the messages loading

If Outlook opens but individual emails remain blank or keep loading, Microsoft identifies AdBlock and uBlock as possible causes:

1. Open Outlook.com in Microsoft Edge or another browser.
2. If the messages load there, disable the ad blocker for Outlook.com in your usual browser.
3. Refresh Outlook.com.
4. If that fails, temporarily disable other browser extensions and test again. Firefox add-ons can also prevent the inbox from loading. ^2^

Secure the account

An unexplained language change does not prove that the account was accessed by someone else, but it should be checked:

1. Open the Microsoft account Recent activity page and review the last 30 days of sign-ins, devices, and application activity.
2. If anything is unfamiliar, first run a full antivirus scan on the computer.
3. Change the Microsoft account password after that scan.
4. Review Outlook settings for unfamiliar forwarding, connected accounts, and automatic replies. Microsoft’s compromised-account procedure specifically recommends checking these settings. ^3^
5. Update the account’s security information and remove unrecognized trusted devices. ^4^

If this is a work or school mailbox and the language option is unavailable or disabled, the organization may control it; contact the Microsoft 365 administrator. ^5^
