Sending, receiving, and organizing email in Outlook.com
For Outlook on the web or new Outlook, change the display language here:
- Select Settings.
- Go to General > Language and time.
- In Language (Country/Region), select English.
- Select Save.
If the issue is in classic Outlook on Windows:
- Open Outlook.
- Select File > Options > Language.
- Under Office display language, add or select English.
- Under Office authoring languages and proofing, add or select English if needed.
Because the interface changed unexpectedly, also review account settings for signs of unauthorized changes:
- In Outlook settings, review Rules and remove anything not created intentionally.
- Review Forwarding and IMAP and remove unknown settings.
- Review Junk safe/block lists and remove unknown entries.
- Change the account password.
- Enable two-step verification.
- Use Sign out everywhere to end active sessions. This can take up to 24 hours to fully take effect.
