How do I monitor my Microsoft 365 shared mailboxes?

Shared mailboxes are excellent for collaboration within organizations and allow multiple users to send and receive emails through them. However, they can cause security issues because of the ease of access. You need to audit your organization's shared mailboxes to know which user accessed a shared mailbox and when. 


Exchange Reporter Plus gives you granular reports on:

  • Shared mailboxes
  • Shared mailbox permissions
  • Send as activities in shared mailboxes
  • Shared mailbox activities
  • Inactive shared mailboxes
  • Top used shared mailboxes
  • Shared mailbox sizes
  • Email activity
  • Mails sent and received

The Shared Mailbox Access report (fig. 1) shows you who accessed the mailbox, when the operation performed, and more.
