Office 365 Groups Mail

Published by Microsoft

High risk

The Office 365 Groups Mail connector allows users to work with data located in a Office 365 Group mailbox. The functionality in this connector works independently from a single user's personal mailbox and allows users to work with any Group they can access within their organization. The connector works off the Microsoft Graph API, and uses terminology specified in a Office 365 Groups documentation within the Graph API. Learn more in the connector documentation.

Security assessment

Plutonium assessed this connector for permissions, capabilities, and security-relevant behavior.

  • Reads your private information: This connector can read data the connected service holds about you - documents, messages, contact lists, source code, customer records, or saved profile details - and pass it back to the AI.
  • Can change or update your information: This connector can edit, rename, overwrite, or otherwise modify records in the connected service. If a request gets manipulated, your data could be altered without you noticing.
  • Can permanently delete data: This connector can erase records, files, or accounts. Once deleted the data may be unrecoverable - even an accidental request can cause permanent loss.
  • Can send messages as you: This connector can post messages, emails, or notifications on your behalf. Recipients will believe the message came from you, which makes phishing or social-engineering risks higher.
