Using classic Outlook for Windows in business environments
Hi Adrian,
I hope you’ve been well.
Based on your description, the one-hour discrepancy may occur because the current (UTC−08:00) Pacific Time (US & Canada) setting still follows the seasonal time change, while most of British Columbia will remain at UTC−7 after November 1, 2026.
Since this is a user-to-user support forum, I’m unable to confirm whether Microsoft will add a new British Columbia time-zone option or automatically update the existing Pacific Time setting.
In the meantime, I recommend checking that the time-zone settings are consistent in both locations:
- In Outlook on the web, go to Settings > Calendar > View > Time zones.
- In Microsoft Bookings, go to Booking page > Region and time zone settings.
- Check whether a new British Columbia-specific time-zone option becomes available and select it in both locations if applicable.
- Continue testing appointments scheduled after November 1, 2026, including how they appear in the confirmation email and the client’s calendar.
I would not recommend manually adjusting appointment times by one hour or selecting an unrelated UTC−7 time zone as a permanent workaround, as this could cause additional discrepancies after the time-zone data is updated.
For official confirmation regarding the planned Bookings support and the recommended time-zone configuration, or for further investigation into the one-hour discrepancy, your Microsoft 365 administrator can open a support request with Microsoft Support through the Microsoft 365 Admin Center > Support > Help & support. When contacting support, it would be helpful to include screenshots showing the appointment time in Bookings, the business calendar, and the client’s calendar.
