Recovering a deleted email may take a few steps. Please follow the instructions below:

1. Check your Deleted Items and Trash folders for a copy of the email.
2. Look for the email in other folders, especially if you used a filter or mailbox rule directing it.
3. Empty messages from Junk Email and Spam folders, which will send messages directly to the Deleted Items folder.
4. Consider using an email recovery tool to locate the accidentally deleted email.
