A powerful email and collaboration platform developed by Microsoft, designed to support enterprise-level communication and productivity. Miscellaneous topics that do not fit into specific categories.
To better understand your situation, could you please share some information:
- Are you using the Outlook desktop application or Outlook on the web or the Mail app on Windows or a mobile device?
- What is your email address ending? Is it a Microsoft account (like @outlook.com, @hotmail.com) or a custom domain managed through a Microsoft 365 Business plan (like @yourcompany.com)?
- Is this happening with all recipients, or only specific ones? For example, does it only happen when you send to Gmail users, or people at a certain company?
- Are you receiving any bounce-back messages or "Undeliverable" reports after sending? These messages often contain clues about why the email was rejected or marked as spam.
I look forward to your response.
