Currently in Standard Mail template (StdR10Mail) by default language "en" as English is hard coded,
however when user enables the Alternate name display property in location document. Alternate Name appears properly in Mail Body content, but Alternate name does not appear in Inbox under "Who" column.
To achieve the same we have added the formula "@GetProfileField ("calendarprofile"; "$LangOwner")" for field "Translate_TemplateLanguage" in form (SortNameCompute), and it worked fine now.
Please update the standard template so that we don't need to customize the template for displaying Alternate display name at View level.
