One of the customer has reported a bug that was found in the Outlook 2016 calendar using ActiveSync accounts.
When an appointment is created in Outlook and the entire day option is saved, the appointment is saved one day earlier from the appointment set. For example., if the user wants to create a new appointment on 26 Jan and has the entire day option enabled and saved it, the Outlook Calendar initially saves it on 26 Jan. After a while, Outlook reflects on 25 Jan. A check on the Webmail shows likewise.
The user then tries to save it again, it went to 24 Jan because the appointment was set to 25 Jan. It keeps saving a day earlier.
Our timezone is +8 hrs. A check on the PC and Webmail account shows both ends are set to +8 hrs timezone. Hence, it is not a problem on the timezone setting. We also tried on another PC. It also reflects the same problem.
Can this be resolved quickly?
