Shared Mailbox Calendar ' when new event is created' trigger is not working

Business Scenario:

Create new event in SharePoint Calendar event when new event is received in Shared Mailbox calendar.

Implemented Solution:

Create and configure Microsoft Flow that triggers when an outlook event is created in Shared Mailbox calendar. Connect outlook event trigger to Shared Mailbox calendar using Calendar ID and use Shared Mailbox owner account to set up trigger connection.

 

Problem:

We created new automated flow that gets triggered when new event is created in outlook. Configured all actions and connections to Outlook as well as SharePoint Calendar list and saved the flow. It runs on a couple of occasions and then start throwing exception as shown below:

Hi @NiravNvs ,

 

Unfortunately, the current When a new event is created only supports the configuration of a personal calendar, does not support group calendar or shared Mailbox calendar.

If you want similar functionality to be supported by MS Flow, please consider voting for a similar idea:

Hi @NiravNvs 
I am not sure if this is actually a point anymore for you, but there is a workaround how to do this:
First of all you must open the Shared Mailbox in Outlook (Online) and click on the three dots - "Sharing and permissions"

Then share the calendar with your user account and select "can edit" as permission.
Now you should be able to select the calendar in your Power Automate flow from the dropdown. For the trigger "when a new event is created" it should also work, for others like "when an upcoming event is starting soon" you can select the calendar, but the flow does not start somehow.

As I said, it is just a workaround, hopefully Microsoft will add the functionallity by default in the future.

Best regards
Marvin
