- Scenario
- A user is looking to understand the differences in mailbox capacities between free and paid Microsoft accounts, set up a professional company domain, and manage billing options.
- Observed behavior
- Users are unsure about the storage constraints of free Hotmail accounts versus Microsoft 365 plans, and whether they can manually configure capacity or change their email address domain.
Verify whether your current email is a free consumer account (like @hotmail.com or @outlook.com) or an active Microsoft 365 Personal, Family, or Business subscription, as features and storage limits vary heavily by account type.
Understand and Manage Mailbox Storage Capacity
Determine your mailbox limits based on your plan and explore options for increasing storage.
Hotmail (Outlook.com) is exclusively a consumer service. Free accounts come with limited storage, which cannot be manually configured or adjusted. To get more space, you must upgrade your plan.
Microsoft 365 Business administrators can reduce a specific user's mailbox size within the admin center, but cannot increase it beyond the maximum capacity dictated by their subscription tier (usually 50 GB or 100 GB).
Log in to Outlook.com, click the gear icon for Settings, navigate to 'General', and select 'Storage' to view your current usage.
If you need more than the free limit, purchase a Microsoft 365 Personal or Family subscription to automatically upgrade your consumer mailbox capacity to 50 GB.
For business accounts, log in to the Microsoft 365 Admin Center, go to 'Users' > 'Active users', select a user, and manage their Mailbox settings to apply customized (but not exceeding plan max) size limits.
Configure a Custom Company Domain
Change the part of your email address after the @ symbol to a personalized or company name.
Manage Subscription Renewals and Payments
Keep your email service active by updating your payment methods or redeeming a product key.

Frequently Asked Questions
Can I manually increase the mailbox capacity of my free Hotmail account?
No, free Outlook.com and Hotmail accounts have a fixed storage limit that cannot be adjusted manually. To get more space, you must upgrade to a Microsoft 365 Personal or Family subscription.
Is Hotmail available for business use?
Hotmail (now Outlook.com) is strictly a consumer service. If you need business-grade email hosting with larger capacities (50 GB or 100 GB) and admin management controls, you should look into Microsoft 365 Business plans.

You can renew your subscription by logging into the Microsoft Account portal, navigating to 'Services & subscriptions', clicking 'Manage' on your current plan, and choosing the option to redeem a prepaid product key or card.
