The OWA language setting bug still is not fixed.
If you set the language with the cmdlets:
Set-OwaVirtualDirectory -identity "Owa (Default Web Site)" -LogonAndErrorLanguage 2057
and:
Set-OwaVirtualDirectory -identity "Owa (Default Web Site)" -DefaultClientLanguage 2057
users cannot go to 'see all options' in OWA. When they do, they get asked to set their language again and then get a 'page cannot be displayed' error.
I have had to unset it again by setting the language to 0.
Please, please, please can someone fix this. The ability to set the default language for OWA is very desireable for customers as they'd prefer that their users do not have to do this the first time they use OWA. You'd be amazed at how many users call the helpdesk.
