Where can I find the Calendar ID for a calendar to Create a Teams Meeting

[Anonymous]

Note: This is not actually solved - see addendum below.

I'm trying to work around the fact that Bookings will not allow the customer to add guests to an appointment.

What the process should be: Emails are sent to external teams of from two to five people, asking them as a group to schedule a time with our staff to meet. Someone from the team uses our Bookings to schedule this meeting. When that happens, the other team members should also receive a confirmation, so they can put the meeting on their calendars.

We have been relying on messaging to the person who schedules to forward the meeting information, however, as we know who should get these invites, we should be able to come up with a way to notify everyone ourselves.

Ideally, we could use the date/time info from Bookings to create a Teams meeting and send out invites. To create a Teams meeting, the Calendar id is required.

I am a delegate on the Bookings calendar, and I see it in my list of calendars in Outlook

Is there a way to determine the Calendar ID so I can enter it as a custom value?

Hi @Anonymous 

You could use get calendars and filter on the output?

That actually works.  I added rows to a spreadsheet with columns for ID and Display Name and I now have IDs for all my calendars.  The IDs are all 152 characters long, btw.  

I made a manual flow that looks like this:

I spoke too soon.  I do have something that calls itself a Calendar ID, however ... when I try to Save my Flow, I get this:

Hi @Anonymous 

Does it just need the calendar name then and not the id?

You would think so, but that's what I tried first. Changing it to the Display Name of the calendar gets me this variation when I try to save.

I have the ID and Display name for 23 calendars in my spreadsheet.  I'm not sure what special sauce I need to get these to where Power Automate can see them.

Hi @Anonymous 

I’m struggling to see that on my phone. If you run the action with fixed values and then look at the history, what is the data in the input? Name or id? Or something else?

Here's the text from that error message:

Flow save failed with code 'OpenApiOperationParameterValidationFailed' and message 'Input parameter 'calendarid' validation failed in workflow operation 'Create_a_Teams_meeting': The API operation 'CreateTeamsMeeting' requires the property 'calendarid' to be set to one of its defined enum values '["Birthdays","Calendar","United States holidays"]' but is set to 'TEALS Program Southwest Region'.'.

It wants the name to be on the enumerated list. When I use Calendar, it shows the name, like so:

So, the question seems to be how to get this calendar, where I'm a delegate, onto that enumerated list.

You’ve passed a calendar name that’s not an option? TEALS Program Southwest Region? Can you create that one manually?

It's already created.  It's a Bookings calendar that I have set myself as a delegate on.  It shows up in Outlook under My Calendars, yet is not in the enumerated list.

I tried uninstalling and reinstalling the entire Office suite (after restarting Outlook, and restarting the computer failed to resolve this).
