Solution 1Recommended

Install the Latest OS and Microsoft 365 Updates

Global time zone definitions are maintained by OS vendors and Microsoft. Updating your system ensures you have the latest Fiji time zone rules.

Time zone and Daylight Saving Time (DST) changes are distributed globally through official system patches. Because Fiji is no longer observing DST, your device requires the newest patch to process calendar conversions accurately.

1
Check for operating system updates

Navigate to your system settings (Windows Update on PC, or System Settings > General > Software Update on macOS) and install the latest available updates.

2
Update Microsoft 365 apps

Open Microsoft Outlook, go to File > Office Account, click on the Update Options button, and select Update Now.

3
Restart Microsoft Outlook

Close Outlook completely and reopen it to allow the new time zone and DST rules to apply to your existing calendar events.

Install the Latest OS and Microsoft 365 Updates
Update Completion: Once the updates are fully applied, Outlook will automatically recalculate and display the correct meeting times for all Fiji-based appointments.

Frequently Asked Questions

Why is my Outlook calendar showing the wrong time for meetings with Fiji?

Fiji recently stopped observing daylight saving time (DST). If your operating system or Microsoft Outlook has not received the latest global time zone patch, it will continue to incorrectly apply the old DST offset, shifting meetings by an hour.

Can I manually fix the Fiji time zone issue by changing my own computer's time?

No, manually shifting your own local clock or time zone will not resolve the underlying issue for cross-timezone scheduling. The problem stems from outdated global time zone definitions within the software, which strictly requires an official update.

How often does Microsoft update global time zone definitions in Outlook?

Microsoft typically releases time zone and DST updates periodically as part of their regular Windows and Microsoft 365 update cycles, specifically triggered when governments announce official changes to their time policies.

What should I do if the latest Microsoft updates don't fix the calendar times?

If you have installed all available system and Office updates and the calendar still shows incorrect times, contact your IT administrator. They must open a direct support ticket with Microsoft to request a specific time zone patch for your tenant.
