Frequently Asked Questions

Can I use Outlook on my mobile phone without Microsoft 365?

Yes, the Microsoft Outlook app is free to download and use on iOS and Android devices for basic email management. You do not need a paid Microsoft 365 subscription to use it.

Will I lose my saved files if I cancel my Microsoft 365 subscription?

Canceling your subscription automatically reduces your OneDrive cloud storage limit to the free 5GB tier. If your stored files exceed this limit, you must download them to your local device before canceling, or your account may be restricted.

Microsoft's billing team can review your account history to determine eligibility for a refund, especially if the subscription has not been utilized on a personal device. You must contact them directly via the Microsoft Support 'Contact Us' page to initiate a review.
