Microsoft’s Canada Timezone Troubles Leave Admins Fixing Calendars, Pretending They’re In Bogota

November 2, 2026

Microsoft is scrambling to fix time-zone problems across Outlook, Power Automate, Fabric, SharePoint and other products after parts of Canada stopped observing seasonal clock changes on November 1. “The company has confirmed problems across a chunk of its software estate, leaving some customers facing incorrect times, broken schedules and a collection of workarounds while Redmond catches up,” reports The Register. From the report: Outlook users have been left with the most homework. Switching to the new Canadian time zones won’t automatically update existing calendar entries, meaning that meetings scheduled after November 1 are potentially an hour out of whack. Microsoft advises users to change their Outlook calendar time zone, then update upcoming events and meetings to use it. For meetings involving other people, only the organizer can make the change.

Recurring meetings come with an additional treat: changing the time zone resets any previously moved occurrences, which then have to be recreated. Anyone with a calendar full of recurring meetings may wish to put the kettle on first. Microsoft is working on an Exchange Online PowerShell cmdlet to remediate non-recurring meetings, but according to its guidance, that’s not due until later this week. A fix for recurring meetings remains “in development,” with an ETA yet to be confirmed.

Things get stranger with Power Automate and Fabric, where Microsoft’s temporary fix involves pretending you’re somewhere else entirely. Depending on the product and province, that could mean Saskatchewan, Arizona or, for Manitobans, Bogota. Because apparently time zones weren’t confusing enough already. SharePoint On-Prem customers, meanwhile, have to wait until November 10 for the correct time zones to arrive, while Power Pages users could see server-formatted dates appear an hour out until a service fix lands. Microsoft’s current milestone for that is December 12.
