Set default client language for Outlook Web App (OWA) for all users, here you need to use Language Codes witch can be found here: http://technet.microsoft.com/en-us/library/aa997435.aspx. Once the default client language is specified when the users try to login for the first time in OWA, they are not prompted to choose a language and OWA Time Zone is picked up from the time zone of Client Access Server.

Set-OWAVirtualDirectory “OWA (Default Web Site)” -DefaultClientLanguage 2057

    Why have you used “-Languages” (with an S) when it should just be -Language?

    When I try to null out the language setting for a mailbox I get the following error. I don’t think it’s really critical to my situation though anyway because when I null out TimeZone, TimeFormat & DateFormat it gives the user to option to set language & timezone when they next logon to OWA which is all I was after anyway.


    Set-MailboxRegionalConfiguration USERID -Language $null

    Cannot validate argument on parameter ‘Language’. The argument is null. Supply a non-null argument and try the command
    again.
    + CategoryInfo : InvalidData: (:) [Set-MailboxRegionalConfiguration], ParameterBindingValidationException
    + FullyQualifiedErrorId : ParameterArgumentValidationError,Set-MailboxRegionalConfiguration

    Thanks,

    Conor.
