No. It is terrible, a webview around the shitty outlook.com web UI, which is cluttered, inconvenient, and often buggy, especially when rich text editing is needed. Also the Bcc field is hidden and needs some weird incantations to display the field. A steming platform, as it can be read in the emails.

Outlook Express was almost peak outlook usability, and is on the decline ever since. More useless features, and ever worse GUI.
