Microsoft 365 Premium bundles Copilot with the full Office apps, Outlook triage, workflow automation and some agentic AI usage, plus up to 6 TB of shared OneDrive.
Pick it if: your inbox and calendar are in Outlook and you'd use Word and Excel too.
Where it falls short: Agentic AI usage is limited on Premium, and Copilot AI is for the account owner only.
