Outlook Free includes email and calendar, 15 GB of mailbox storage, 5 GB of cloud storage, and core security features such as spam filters. Shared calendars and video meeting support are listed. Outlook can connect Outlook.com, Gmail, Yahoo!, iCloud, and other mail services, and scans links and attachments for threats. Focused inbox, sweep, snooze, and flags help organize email, while access to Word, Excel, PowerPoint, and OneDrive files is also included. Copilot can draft messages and help adjust tone, length, and clarity, but in Outlook it currently works with outlook.com, hotmail.com, live.com, and msn.com addresses. Microsoft 365 Personal costs $9.99 a month, billed monthly, and includes 1 TB of storage and use on five devices.

UCals is an AI calendar assistant that manages schedules through natural-language conversation. One instruction can make multiple calendar changes, and later messages can use earlier conversational context. Its plan covers 11 life categories, including work, meals, exercise, and travel. Two-way synchronization is available with Google Calendar, Apple Calendar, and Microsoft Outlook. Tools include conflict detection, travel-time calculation, multi-currency cost tracking, location intelligence, learned preferences, and linked events. UCals displays before-and-after details for changes, and saying “undo” reverts the last change. Its MCP server connects calendars to Claude Desktop, ChatGPT, Cursor, and other compatible assistants. Platforms listed are Android, iOS, macOS, Windows, and an API. UCals says it uses OAuth 2.0, does not store calendar passwords, encrypts data in transit and at rest, and does not sell, share, or train on calendar data. ICS export and priority support are included. A 14-day trial is offered. The Single plan costs $15 a month, billed monthly.
