Hi anonymous user

Have you checked if the items can be found in Recover Deleted Items of the shared mailbox? Please note that: 'folders' can't be 'recovered', only messages
Or in Exchange server side: Recover deleted messages in a user's mailbox in Exchange Online

We could refer to the methods introduced in this link to recover deleted items in O365. Recover deleted mail items – Office 365

2. Recovering deleted mail items by using MFCMAPI utility.
