How to manage events in a shared mailbox using Power Automate

Spoiler

We have now the 4th generation of event-related actions in Power Automate but still, it is not straight forward to use them for a shared mailbox's calendar. 

I hope this simple workaround will help you before we get a dedicated set of actions for shared mailboxes from Microsoft.  

To be able to add, search, update, and delete events in the shared mailbox's calendar, follow these steps:

1. If you have full access to the shared mailbox, open its calendar in the web browser.
   You can use this URL and replace the e-mail of the shared mailbox given here as an example https://outlook.office.com/calendar/shared_mailbox@your.domain.com,
2. Use the Sharing permission option as shown below,
   
   
3. Search your account and share the calendar with "Can edit" permission, as shown below,
   
4. When you receive the invitation from your shared mailbox, please accept it,
   
   
5. Now go back to your flow and use the connection to your account,
6. Whenever you choose "Office 365 Outlook", event-related action, you can select the shared calendar.
   

And remember, this is just a workaround with all its drawbacks.

I hope this can help you.
