Rename an existing email folder
AI agents use outlook_rename_folder to create or update resources in Outlook — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Outlook environment.
This tool modifies folder properties (the name) reversibly—renaming can be undone by renaming again. It does not delete data, execute code, move money, or trigger external operations.
From the tool's definition Tool name 'outlook_rename_folder' and description 'Rename an existing email folder' directly indicate modification of existing folder metadata.

"max": 30,
"scope": "grant"
}
]
