Outlook on the Web – Office 365 Exchange Online and Recent improvements to Outlook on the Web (the new name for OWA in Exchange 2016 and Office 365) have made it more discoverable as well.
The Recover Deleted Items option in Outlook on the Web (OWA) is indeed not directly visible but still “hidden” in a convenient and easy to remember location. In OWA, there is no such tab and I can’t find the “Recover Deleted Items” button anywhere. When this happens in Outlook, I can select the Folder tab and then choose: Recover Deleted Items. I’ve accidentally permanently deleted an email when using Outlook Web App (OWA).
