Common Causes

When your Outlook Calendar availability appears incorrectly to colleagues in different Australian time zones, it can lead to missed meetings and scheduling confusion. This usually happens when Outlook is set to the wrong time zone or when your calendar settings aren't syncing correctly across devices.

Quick Fix Steps

Check that your computer's system clock and time zone are set correctly.
Verify your Outlook time zone settings match your current location.
Restart Outlook to force a calendar sync.
Ask a colleague to check if your availability now displays correctly.

Detailed Instructions

Check your Windows time zone settings

Select Start, then select Settings.
Go to Time & language > Date & time.
Ensure Set time zone automatically is turned on, or manually select your correct Australian time zone (for example, (UTC+10:00) Brisbane, Canberra, Melbourne, Sydney).
If you changed the time zone, restart Outlook.

Check your Mac time zone settings

Select the Apple menu System Settings (or System Preferences).
Go to General > Date & Time.
Ensure Set time zone automatically using your current location is enabled.
Restart Outlook for Mac.

Verify Outlook time zone settings

Open Outlook.
Select File > Options > Calendar.
Under Time zones, check that the correct time zone is selected for your location.
If you travel between Australian states regularly, select Show a second time zone and choose the relevant zone for your colleagues.
Select OK to save changes.

Check calendar sharing permissions

In Outlook, select Calendar from the bottom navigation pane.
Right-click your calendar and select Sharing Permissions.
Ensure your colleagues have the correct permission level to view your free/busy information.
Select OK to apply changes.

Daylight saving time changes can affect calendar availability in states like New South Wales, Victoria, South Australia, Tasmania, and the Australian Capital Territory. Queensland, Western Australia, and the Northern Territory do not observe daylight saving.

Changing your computer's time zone can affect other applications and scheduled tasks. Only change these settings if you are sure of the correct time zone for your location.
