Microsoft Outlook introduces ads for non-subscribers

Following the discontinuation of the Windows Mail application at the end of 2024, many users have transitioned to the new Outlook. This version, which functions essentially as a web-based application within a window, includes advertisements in the inbox for users who do not have a Microsoft 365 subscription.

While the new Outlook offers a modern interface, it lacks certain professional features found in the classic version, such as support for COM add-ins used by CRM and billing software, more robust offline modes, and full PST file support. The classic, ad-free Outlook remains available through one-time purchases, such as Office 2024 Professional Plus.
