@VentiloFred
i got other ideas that may work for you (both work fine on my side)
Office365Outlook.V4CalendarPostItem(
LookUp(Office365Outlook.CalendarGetTables().value, DisplayName = "Calendar").Name,
"Test Post item",
Text(Now(), DateTimeFormat.UTC),
Text(DateAdd( Now(), 10, Minutes ), DateTimeFormat.UTC),
"(UTC+01:00) Brussels, Copenhagen, Madrid, Paris"
)
or
Office365Outlook.V4CalendarPostItem(
LookUp(Office365Outlook.CalendarGetTables().value, DisplayName = "Calendar").Name,
"Test Post item",
DateTimeValue(Text(Now(), DateTimeFormat.UTC)),
DateTimeValue(Text(DateAdd( Now(), 10, Minutes ), DateTimeFormat.UTC)),
"(UTC+01:00) Brussels, Copenhagen, Madrid, Paris"
)
