Subble checks desktop Office use and mailbox size to find people who only need Microsoft 365 F3 instead of E3, or Office 365 E1 instead of E3.
Check who needs paid Copilot
Find people who only use Copilot Chat on the web and can move to Microsoft 365 Copilot Chat, plus paid Copilot licences nobody uses.
Remove licences already included
Subble finds overlapping licences, such as Power BI Pro already included in E5, or two Microsoft 365 suites assigned to one person.
