Get calendar

(1) Share

Posted on by CU22030726-0

Hi,

I want to build a calendar in Power Apps. (show only busy/free used Outlook calendar user)
What function can I use to retrieve calendar information if some people have shared calendars only on a "can view when busy" basis?

This is sufficient for me because I want to be able to retrieve this information and post it to the gallery. However, none of the functions I've tried to use have worked because the calendar must be fully shared. (Get Event, Get Calendar Event, etc.) and how can I do this?

I also tried using the FindMeetingTimes function, but it doesn't return all the values, especially if I want to retrieve a longer period of time.

Can you suggest a function/mechanism I can use to retrieve these calendars? (Ideally, an email address as the search parameter.)

I'm new here, thank you for your help.

From what I can tell, this probably doesn’t work because when someone shares their Outlook calendar as “busy/free only”, you’re not really getting access to the calendar itself — just a rough availability signal. So things like Get Events don’t return anything, even though the calendar looks shared.
What seems to work better in this case is using Microsoft Graph (for example the getSchedule endpoint), usually through Power Automate. It’s more about availability than events, which fits the busy/free scenario much better.
If you want to understand this deeper or see how others solve it, digging into it with Copilot can actually be pretty helpful.

Core Problem

You want:

Get busy/free (availability)

For users who only shared calendar as “Can view when busy”

But:

Get events / Get calendar events → require full access

Shared “free/busy” does NOT expose event details

Standard Outlook connector cannot read availability-only calendars

Key Reality

There is NO direct Power Apps / Outlook connector function
to retrieve free/busy data from “availability-only” shared calendars

What Actually Works

Use Microsoft Graph API (Best & Correct Approach)

Use:

/calendar/getSchedule

via Microsoft Graph API

What it returns

Free / Busy blocks

Time slots

Works with availability-only sharing

Multiple users at once

Example Request

POST https://graph.microsoft.com/v1.0/me/calendar/getSchedule
{
"schedules": ["user1@domain.com", "user2@domain.com"],
"startTime": {
"dateTime": "2026-03-24T09:00:00",
"timeZone": "UTC"
},
"endTime": {
"dateTime": "2026-03-24T18:00:00",
"timeZone": "UTC"
},
"availabilityViewInterval": 30
}

Response
"availabilityView": "000111000..."

Where:

0 = Free

1 = Busy

2 = Tentative

3 = OOF

Thanks

Hi,

I couldn't find the query with the example.

Is the query I found the same as in the example?

I found another API request that mentions a calendar. I just can't test it. Could you tell me how I can find the "user-id"?

Thank you for your help.

Regads,

Piotr
