Deletion of Outlook data (how to recover data)

Data that is deleted will be in deleted items in Outlook

If you want to find the data that has been deleted with the compliance solution, you need to go to Deleted Items, and there is an option to restore them. How long they can be restored depends on your organization's setup, but typically for 30 days. (this work for Microso0ft 365)

See below how to do this in the Outlook client and in the Outlook web client
