This article explains how to check the available, or remaining, storage for a SharePoint Online (SPO) Site, Site Collection, or a Team in Microsoft Teams.
In reference to Microsoft Teams Storage, files and folders that you store in a Teams channel are housed in the SPO Site associated with your Team (for example, if you have a Team named "IT Conference" anything shared in any channel in your IT Conference team will be stored in the IT Conference SharePoint Site). To check your available Teams storage, you will need to check the corresponding SPO Site storage by following the instructions in this article.
To see this information for your SPO Site or Site Collection, you must be an owner of that site.
