Microsoft is notifying its Mail and Calendar app users to switch to free web-based Outlook. Many users have reported noticing pop-ups from the app. Microsoft insists users make the migration by December 31, 2024. After that date, the app will only display emails and calendar entries saved until the scheduled date.

The company published a support document emphasizing that the Mail and Calendar app will switch to read-only mode for old data after December 31, 2024.
