Dear @reception,
Thank you for posting your question in the Microsoft Q&A forum.
From your description, I understand that you’re using the new Outlook for Windows and you can’t find any sent emails (it looks like Sent Items is missing or empty), and you’re concerned those sent messages may be lost.
To better assistance, could you please confirm following information:
Are you using a work/school (Microsoft 365) account, or personal account?
Can you see the missing sent emails in Outlook on the web?
Is this happening for one account or multiple accounts in the new Outlook?
Do you send from a shared mailbox or on behalf of another mailbox?
When did you first notice the Sent Items missing/empty (after switching to new Outlook, or after an update)?
In the meantime, I recommend some quick checks below:
1/ Check Outlook on the web first to confirm whether the sent emails are present there.
2/ Check Deleted Items and then use the “Recover items deleted from this folder” option if available. Microsoft provides steps to restore items in the new Outlook from Deleted Items / Recoverable Items.
Please understand that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.
I truly appreciate your patience and understanding. If you have any further questions or need further clarification, please feel free to reach out. I'm looking forward to hearing from you.
Thank you for your cooperation.
