We have an EWS managed API application that creates appointments in Office 365. We just noticed that appointments with a recurrence on them start one day earlier. This never happened before. And it only happens in central and pacific time zones. We process in eastern time zone and it works ok. Normal appointments work fine in any time zone.

When we debug, it shows the correct start date and time zone but when we view it in Outlook or OWA it starts one day earlier. This is not an all day event.

Is this a new feature or a bug? If it is a feature then we will subtract a day from the start on recurring items for any office 365 user.

Any one else have this issue? It just started doing this or we just caught it recently.
