243243* `Team.ReadBasic.All` and `Channel.ReadBasic.All` let Claude list the user's teams and their channels (`teams_list_teams`, `teams_list_channels`), which Claude uses to find the team and channel IDs that the channel-message tools take.

270270### Grant write scopes
271271
272With only read scopes granted, the connector is read-only. To let Claude take actions in Microsoft 365 (sending mail, managing drafts, labels, filters, and calendar events, working with files in OneDrive and SharePoint, and sending Teams chat and channel messages), grant write scopes: add them to the entry's `scope` field and consent them on the app registration from step 1, the same as any other scope. Each write tool appears only when its scope is in the entry's list, so granting a subset of the write scopes exposes a matching subset of the tools, and removing the write scopes from the list returns the connector to read-only. Write tools require Claude Desktop version 1.19367.0 or later, and the Teams write tools require version 1.24012.0 or later.
