There is a support note, if you can find it. Here’s the link. “Starting January 2026,” Google tells users of the world’s most popular email platform, "Gmail will no longer support checking emails from third-party accounts through POP. The option to ‘Check mail from other accounts’ will no longer be available in Gmail on your computer."

The aim is to transform Gmail from a traditional inbox into what Google describes as a “personal, proactive inbox assistant.”
