In this video we'll show you how to change the language to your outlook in office 365. We will change the language via the web interface settings, but we will also show you how to do it with PowerShell.
Using PowerShell you can also solve the annoying error "exchange can not localize default folder(s)".
If you use Outlook (desktop app) in exchange mode (MAPI), automatically you will translate your outolook folders.
