Microsoft's Canada timezone troubles leave admins fixing calendars

Parts of Canada stopped observing daylight saving time on November 1, creating timezone mismatches across Microsoft's software products including Outlook, Exchange Online, Power Automate, and Fabric. Microsoft confirmed the issues leave customers with incorrect times and broken schedules, requiring manual workarounds such as updating calendar entries individually and, in some cases, temporarily changing location settings to unrelated regions like Bogota. Fixes are being rolled out gradually, with some solutions not arriving until mid-December.
