I know that once a user logs in to OWA the first time their time zone needs to be selected. How do we do this via PowerShell/IIS Administration/whatever so this is set without user interaction when they go to OWA the first time? Thanks! Jason

Hello Jason, If you set any default language for individualuser or for all usersthen it setsRegional Settings like time zone, date/time style etc automatically but I dont think so we can set only time zone without setting default language before login into OWA first time. Note: If you set the default language then it will change default folder name (like Inbox, outbox, Sent Item) into that language.

Viewing version When the firest logon on OWA depends on that client sends request header that contains regional language ; In a word, deponed on that client locates regional options; So, I dont agree amit s idea, perhaps I am wrong??? If anything wrong, pls free time to tell me,thank amit; -jack

Set-OwaVirtualDirectory -identity "Owa (Default Web Site)" -DefaultClientLanguage <language code> So if you want it to be English - US, change <language code> to 1033.
