Purpose
Suppose that an Outlook user has access to their personal mailbox and to the additional (shared) mailboxes (usually "Info" <info@company.com>, "Sales" <sales@company.com> etc.) on an Office 365 tenant. When a user deletes an email in the shared mailbox, the deleted email is saved in the "Deleted Items" folder of the user's mailbox, not the shared mailbox's "Deleted Items" folder.
Microsoft provides a solution only for the "classic" desktop Outlook (the DelegateWastebasketStyle option).
This flow ensures that the message deleted from the secondary mailbox will be placed in the "Deleted Items" folder of the secondary mailbox.
Current version: 1.0.3
Installation
- Open Office 365 Power Automate and import the CoolDel.zip file into your flows list as described here.

- The flow uses two connections: "Office 365 Outlook" and "Office 365 Users". You may use existing connections or create new ones as needed.

- Select the Deleted items folder of your personal mailbox in the "Folder" field of the trigger. Populate the "*Inputs" field in the "Compose AllowedMailboxes" action with a JSON array containing the default addresses of additional mailboxes you want to work with. If you want the flow to work with all additional mailboxes, place an empty array [] there.

- Turn on the flow.

Testing
If you have the primary (personal) mailbox "jdoe@contoso.com" and the additional mailbox "sales@contoso.com":
- Open Outlook and navigate to "sales@contoso.com" > "Inbox" [1].
- Delete any email in the "Inbox" folder. Note the deleted email is saved to your personal mailbox "Deleted items" folder.
- Wait 5-10 seconds and navigate to "sales@contoso.com" > "Deleted items". Verify that the message is now there [2].
