Outlook for Mac and iPhone showing meetings an hour off: how to fix it
If Outlook on your Mac or iPhone shows a meeting an hour off while Outlook on the web looks right, the event is stored with the wrong time zone and each app interprets it differently. Fixing the event in your mailbox fixes it in every app.

What people are seeing
Microsoft Q&A threads describe new Outlook for Mac and Outlook for iOS showing Alberta and BC events an hour late after Nov 1, 2026, and the calendar grid disagreeing with the opened event by an hour. New Outlook for Mac needs a recent build, and some builds still label BC as UTC-08:00. Outlook Mobile cannot edit the time zone of an existing event at all.
Why a web app helps
The wrong data sits in your cloud mailbox. This app edits events through your Microsoft account, so it works from any browser, including on a Mac, and you do not install anything. Once the stored time zone is correct, Outlook on Mac, iPhone, Android and the web read the same event.
Limits
- It fixes events, not your device clock. Keep macOS and iOS up to date and check that your calendar time zone setting is right.
- Microsoft 365 and Outlook.com accounts only. Apple Calendar and Google Calendar accounts are not supported, even when the events appear in the Outlook app.

Frequently asked questions
Why does Outlook on Mac or iPhone show a different time than Outlook on the web?
Clients treat the stored time zone differently: classic Outlook follows the Windows zone, while new Outlook for Mac and Outlook for iOS have been reported to show Alberta and BC events an hour off. Correcting the time zone stored on the event in your mailbox fixes it for every app that reads that mailbox.
Why are my Outlook meetings showing an hour late after the time change?
Events you booked before the Windows update are stamped with a US time zone such as Pacific Standard Time. On Nov 1, 2026 the US fell back an hour but British Columbia, Alberta and Manitoba did not, so those events now land an hour away from where you booked them. Existing events do not move to the new zone by themselves.
Can I undo a change?
Yes. Every change is logged with the event ID and the old and new times, and you can undo it for 30 days.
Will Outlook fix my meetings automatically?
No. Microsoft’s guidance says existing events are not migrated automatically and that only the organizer can change an event’s time zone. Microsoft’s free Exchange Online cmdlet covers single (non-recurring) meetings only and has to be run by an administrator.
How much does it cost?
The first 10 events you fix are free. After that it is a one-time $5.99 CAD for every event in your account. There is no subscription.
