Office 365 mailbox size reporting is essential for preventing storage issues, controlling costs, and maintaining optimal performance. Organizations can use Microsoft 365 Admin Center for basic needs, Exchange Admin Center for real-time data, or PowerShell scripts for advanced automation and detailed reporting. Native Office 365 tools have limitations including restricted historical data, no automated alerting, and time-intensive manual processes.
Professional solutions like Promodag Reports provide unlimited historical data, automated reporting, and advanced analytics that go beyond built-in tools.
