Hi @Abdul Rahman ,
Welcome to our forum!
As i know, we can try to find the the deleted items in Deleted Items folder or Recoverable Items folder in Outlook desktop client. More information: Recover deleted items in Outlook for Windows.
If you can't find the item in the Recoverable Items folder, ask your administrator whether it can be recovered. If neither of you can find the item, i'm afraid that the item was probably permanently deleted from your mailbox and can't be recovered.
