I checked my Outlook and it's set to Eastern Standard Time. Office 365 settings are set to Eastern. The SharePoint site where I save my data to a list is the same region. I based the below formula on a Shane Young video. Is this the problem? If it is, why does the item display in the calendar correctly?
Office365Outlook.V4CalendarPostItem(LookUp(Office365Outlook.CalendarGetTables().value, DisplayName = "Calendar").Name, txtNMCustName.Text & " Planning Session", DateAdd(varStart,TimeZoneOffset(), Minutes), DateAdd(varEnd, TimeZoneOffset(),Minutes), "(UTC) Coordinated Universal Time", {location: txtNMStreet.Text & ", " & txtNMCity.Text & " " & txtNMZip.Text, body: txtNMPhone.Text & ", " & txtNMEmail.Text & "<br><br>" & txtNMNotes.Text})
