Thank you for posting your question in the Microsoft Q&A forum.
Regarding that your missing emails only appear when using the Unread filter. I’d like to ask a few quick questions to better understand your situation and assist you more effectively:
- I noticed you posted under a business tag could you confirm if you’re using a business account? If you’re using a personal account, please let me know.
- Does this issue happen to any other user as well ?
- Does the issue occur for all new emails or only from certain senders?
- Have you tried Outlook on the web? If so, does the issue persist there?
- Is the Inbox view sorted or filtered in a way that hides new messages?
- Have you checked whether Focused Inbox is enabled or disabled?
Thank you again for your time and understanding. While my initial response may not resolve the issue immediately, I’d like to gather more details about your situation so I can assist you more effectively.
I really appreciate your patience, and I’m here to help. Looking forward to your response!
