Hi, there is a problem with the culture for the user pages.
The date/time format in the calendar and in the mail messages inbox is set and displayed only in US format: 08/22/2017 09:40 PM.
Give the non US users to see the local culture settings for them like a normal WEB application.
Meaning i am in Croatia and want to have 22.8.2017. 21:40 or dd.mm.yyyy. hh:mm.
