Microsoft Office Outlook Tool: Time Zone Data Update Tool for Microsoft Office Outlook Administrators can update appointments for all users at once using the Exchange Calendar Update tool.
This is similar to the Outlook tool but is used against the server.
Vista and Windows 2008 contain this update but later time zone updates are available for Vista and Windows 2008.
If the time zones are not updated for the 2007 DST changes, appointments created in US time zones and scheduled during the last 3 weeks of March and early April will be off an hour.
“To address this risk, today we are providing additional security updates along with our regular Update Tuesday service.
These security updates are being made available to all customers, including those using older versions of Windows.” Microsoft says it is releasing updates for Windows XP, Windows Vista, and all other more recent unsupported and supported versions of Windows due to an “elevated risk” of attacks that are similar to the Wanna Cry malware.
The patches will be made available on Microsoft’s Download Center or Windows Update.
