How do I track permission changes to Exchange Online mailboxes?

Emails contain business-critical information and as an Exchange admin, you need to ensure that there are no data leaks in your organization. Unauthorized users can misuse mailbox content if they gain access to an important mailbox with no business justification. You need to keep an eye on mailbox permissions to ensure no unauthorized permission change has occurred.

  • Object and properties modified
  • Time of modification
  • Command used
  • Status of modification (success or failure)
