Tips for Outlook Calendar
A calendar link is only useful when the event opens at the intended time and gives the guest enough context to recognize it later.
-
1
Offer both Outlook.com and Microsoft 365 links when the audience includes personal and work accounts.
-
2
Include the ICS option for desktop versions of Outlook.
-
3
Keep the event timezone explicit to avoid daylight-saving errors.
Offer the right choice to every guest
Not every attendee uses Outlook Calendar. Add the other provider links or an ICS fallback so nobody has to retype the event.
