Create an Event V4

Report

Posted on by KC-03041638-0

I have a Power Automate flow that iterates over a rolling date range (using a Do-Until loop) and evaluates each date against a set of conditions. For each date in the loop:

The flow determines whether I am scheduled to work that day.

If the result is false (I do not work that day), the flow then checks my Outlook calendar to see whether an “Unavailable-Not Scheduled” all‑day event already exists on that specific date.

If such an event already exists, the flow does nothing.

If no matching event exists, the flow should create a new all‑day calendar event for that date.

The date being evaluated is stored in a variable (e.g., CurrentDate) that updates on each iteration of the loop.

The main issue I am encountering is with the Outlook “Create an event” action (V3/V4). Although the flow logic works correctly and the rolling date updates as expected, Outlook does not accept dynamic values, variables, or expressions as the Start Time and End Time when creating an all‑day event. The action appears to only accept literal date inputs, causing the flow to fail at runtime when attempting to create events programmatically for dynamic dates.

I have verified that:

The rolling date variable is correctly formatted (yyyy-MM-dd), as is every date in this entire flow.

Calendar events are successfully retrieved and filtered earlier in the flow

The failure occurs specifically at the Create an event step when attempting to use a dynamic date value.

I am looking for guidance on:

Whether there is a supported way to create all‑day Outlook events using dynamic dates in Power Automate
Or whether this is a known limitation of the Outlook V3/V4 connector when used with all‑day events and variables

Any recommendations on supported patterns or connector limitations would be appreciated.

Hi @KC-03041638-0

Have you tried to pass a full date-time, not just a date?

See documentation: Office 365 Outlook - Connectors | Microsoft Learn

Microsoft’s documentation shows examples like:

2017-08-29T04:00:00
2017-08-29T05:00:00

Let me know if it worked!

Hello @KC-03041638-0,

Issue is that you are passing only date it expect date and time due to this it's failing the automation.

formatDateTime(variables('CurrentDate'),'yyyy-MM-ddT00:00:00')

For example, if you want to schedule an event from 08:00 to 09:00, you should format it like this:

Start Date:

formatDateTime(utcNow(),'yyyy-MM-ddT08:00:00')

End Date:

formatDateTime(utcNow(), 'yyyy-MM-ddT09:00:00')

If you want this event to repeat every day, you can set the Recurrence to "Daily". You can also add an Recurrence end date if needed.
