❓ FAQ

Do I need a Microsoft 365 subscription?

Yes. M365 WebApps provides desktop integration for Linux, but you still need a Microsoft 365 account to access Office apps.

Can I use multiple Microsoft accounts?

Yes! Each app uses an isolated browser profile, so you can sign into different apps with different accounts.

What happens when my license expires?

Apps continue to launch, but license validation fails. Renew to continue full functionality.
