I have this big problem, that Office 365 switched to Polish user interface some time ago. And the problem is, that I cannot set it back to English, no matter what I do. I'm Polish and I've paid for Office 365 in Polish currency using a credit card from a Polish bank. But I desperately need my Office 365 in English. My goal is to set English user interface in Microsoft Office 365, to have English formula's names in Excel and English menus in Office 365.
The operating system was installed with Polish language but is now switched to English.
I've tried in the Office 365 language preferences dialog, but Office 365 doesn't follow these settings.
There was over 1 year period, from June 2021 when I've bought my laptop and installed Office 365 on it, when Office 365 was in English, but around 2022/2023 (maybe earlier - I'm not sure) the Office 365 switched interface language into Polish against my will.
