See the following articles for Outlook for Windows or for Outlook on the web. To do so, they use the Recover Deleted Items feature in Outlook or Outlook on the web. Users can recover, or purge, deleted items before the retention time for a deleted item expires. Use Exchange Online PowerShell, as shown above, to change this setting, to increase the period up to a maximum of 30 days. An Exchange Online mailbox keeps deleted items for 14 days, by default.
