Frequently Asked Questions

Why do all-day events sync to Outlook but not hourly events?

This specific issue often stems from how the native Apple Calendar app handles time-zone metadata for specific hours versus all-day flags when communicating with Microsoft's Family Calendar servers.

Will I lose my existing calendar data if I switch to the Outlook app?

No, your calendar data is safely stored on Microsoft's servers. Signing into the Outlook app will simply download and display your existing events automatically.

How can I reset the calendar view in Outlook desktop?

In the Outlook desktop application, navigate to the 'View' tab on the ribbon, select 'View Settings', and click 'Reset Current View' to resolve any display glitches for synced events.

Do events created on Outlook web sync correctly to the iPhone?

Yes, events created in Outlook on the web or the desktop app typically sync perfectly down to the iPhone, regardless of whether they are hourly or all-day events.
