After you install the August 2011 cumulative time zone update for Windows operating systems in a Microsoft Exchange Server 2010 environment, some time zone information in Outlook Web App (OWA) is not synchronized with the installed Windows operating system.
For example, some names of the existing time zones are incorrect, or some names of new time zones are displayed in English only.
Additionally, some time zones are displayed incorrectly in the Current Time Zone list.
For example, OWA displays (UTC +03:00) Tbilisi. However, Tbilisi uses the (UTC +04:00) Tbilisi time zone.
