storage limit in Microsoft teams --- still depending on sharepoint limit

 https://answers.microsoft.com/en-us/msoffice/forum/msoffice_o365admin-mso_teams-mso_o365b/definition-of-unlimited-storage-in-microsoft-teams/a0134d49-2caa-4859-a5f8-51e6e8cd010e

1. When you create a Team in Office 365, you are creating a SPO Site Collection behind the scenes
2. Storage for a single SPO Site Collection in Office 365 can be up to 25 TB
3. The quota you have in total for SPO is 1 TB + # Users x 500 MB
4. So while is true a SPO Site Collection can store up to 25 TB, this is not going to happen if you don't have 25 TB of quota storage in your SPO tenant
