Although Outlook.com is free to use, it doesn’t come with infinite storage. The free tier only offers 15GB of space, which, even though it should be enough for most home users, depending on how you use the service, the day may come when the space will run out, even more now that Microsoft plans to change what files count toward the quota in early 2023.
If you want to stay informed on the space usage in your account, the Outlook settings include a page that shows how much storage you are using and options to free up space.
This guide will teach you the steps to check the storage usage of your Outlook.com account.
Check your Outook account storage usage
To determine the storage usage of your Outlook web account, use these steps:
Sign in with your credentials (as needed).
Click the Settings (gear) button on the top-right corner.
Select the “View all Outlook settings” option at the bottom.
Click on General.
Click on Storage.
Confirm the storage usage for your inbox, sent, and deleted items in Outlook.com.
(Optional) Use the Empty option to free up space by removing deleted, sent, archive, and inbox items.
Once you complete the steps, the settings page will display the storage usage and how much space you have left in your account.
If you’re running low on space, Microsoft offers an additional 50GB when you sign up for a Microsoft 365 subscription.
