Outlook calendar reminders pop on one workstation hours late

Minimal guidance for messy support realities.

Scenario

A single workstation shows appointment reminders long after the scheduled time even though the calendar data itself is current.

Recommended Resolution Path

  1. Verify the calendar item time and time zone in Outlook on the web first.
  2. Check Windows time, regional settings, and Outlook reminder options on the affected device.
  3. Start Outlook with add-ins disabled to rule out third-party interference.
  4. If only one profile is affected, recreate the Outlook profile and document the result.

Technician Notes

Confirm the result, document the root cause, and record any preventative action worth standardizing.
