Hi Paul,
Thanks for posting your question in the Microsoft Q&A Forum, and for sharing your build details. I understand how frustrating it is when the Drafts folder shows a lingering count (1–2) even after it’s been emptied.
Try to Sign in to the same mailbox at https://outlook.office.com or https://outlook.live.com. If OWA shows 0 while the Mac app shows 1–2, the issue is local cache/index in Outlook for Mac. You can also try to delete all your drafts in there.
Please also Ensure you’re viewing Drafts for the intended account (if you access multiple account to your Legacy Outlook. Also set view filter to All to make sure no filter is hiding messages.
You can also contact support for further assistance. Here are the steps to contact Microsoft Support:
- Go to Contact Support.
- Type “email stuck in draft” > Scroll down and click Contact Support (please skip all troubleshooting steps or similar articles if you just want to contact Microsoft Support).
- Sign in > Select Products and Services > Other Products/Microsoft 365 and Office (> Outlook) > Chat with a support agent in your web browser.
