Legacy Mac Email Clients Break When Microsoft Deprecates Old Auth Methods
Spark Classic stopped working with Microsoft accounts after Microsoft upgraded its connection method, and the vendor confirmed it will not update the legacy client to support the new Graph-based authentication, forcing users toward a heavier Electron-based desktop app or an entirely different email client. This reflects a structural risk for any lightweight native client that depends on an OAuth or API method a platform vendor can unilaterally deprecate.

Available alternatives often have worse ergonomics, such as a heavier resource footprint or clunkier interface, leaving users with only unappealing options.
