Who it is for
Microsoft 365 users who run their day out of Outlook and coordinate meetings with other people.
Outlook Calendar
Outlook scheduling, availability checks, and meeting updates
Overview
What Outlook Calendar does
This connector, published by OpenAI, works through a connected Microsoft Outlook account. It can summarize what a day holds, compare availability between people, and gather the context needed before a meeting begins. It also explains Outlook's own status semantics when asked about them.
Write access covers the usual calendar changes: creating an event, moving one, and cancelling one. Six published skills sit on top, aimed at daily briefings, freeing up time, group scheduling, meeting preparation, shared calendars, and general calendar work. The connector is marked interactive, so the exchange can continue across several turns.
What stands out
Several named skills sit on top of one connection, each pointed at a specific calendar task such as group scheduling or clearing time.

Where Outlook Calendar is listed
Outlook Calendar is listed in the ChatGPT apps directory only. OpenAI has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
