Microsoft 365 Shared Mailbox Reports

A shared mailbox, as the name implies, is a mailbox that multiple users can access to send and receive emails. A shared mailbox is very handy, as it allows multiple people to answer customer queries, which will be sent to a common email address. But, of course, if multiple people have access to one mailbox, it's necessary to keep tabs on who accesses it and when to keep your Microsoft 365 environment secure.

With M365 Manager Plus, the complete Microsoft 365 solution, these reports can be scheduled to run at fixed intervals, emailed to administrators, and exported to CSV, XLSX (Microsoft Excel), PDF (Adobe Acrobat), or HTML formats.

M365 Manager Plus provides the following reports:

• Shared mailboxes
• Shared mailbox access
• Send as shared mailbox
• Shared mailbox activities
• Inactive shared mailboxes
• Top used shared mailboxes
• Shared mailbox size
• Shared mailbox email activity

• Mails received
