ISSUE
Starting in 2025, Microsoft 365 consumer installs have new Outlook only and don't include classic Outlook. If you installed Microsoft 365 in a localized version and then installed classic Outlook via the standalone download, it's display language is English.
The standalone download link is referenced in this article, You can't open classic Outlook on a new Windows PC.
The reason this issue occurred is because the standalone download link used en-us "clcid" instead of the appropriate locale
STATUS: FIXED
The Office Team fixed the standalone “Download” link for the localized versions by adding a dropdown picker to pick the language to install at You can't open classic Outlook on a new Windows PC.
Although the standalone download is now fixed, there are issues installing from the Store. Installing from the Store may pull down the wrong language. For instance, if you try to install English, you may get Portuguese. The Office Team says that the Store fix will begin rolling out, starting Monday April 14, 2025. Until that fix completes rolling out, please install from the standalone download.
