Mobile Productivity and Cross-Device Integration
Microsoft 365 doesn’t limit you to a desktop. You can download its mobile apps on iOS and Android to edit Word docs, join Teams calls, check emails in Outlook, or upload files to OneDrive all on the go.
Additionally, files stay synced across devices. Start editing a document on your desktop and continue later from your phone without losing progress. That level of continuity is crucial for staying productive during travel or when switching between workstations.
