Creating restricted channels within a team for confidential discussions or projects
Dear Amanda,
As an Independent Advisor and community user, I'll help you with your question.
Each private channel it will create a new SharePoint site, for private channels you have to manage their storage with the SharePoint management shell, you can see all private sites just through PowerShell, so open Powershell as admin (should be better on windows 10), then run followings commands:
Install-Module -Name Microsoft.Online.Sharepoint.Powershell
Connect-SPOService -Url https://tenantName-admin.sharepoint.com #you should change tenantName with your own tenant name.
with below command you will see all site in your tenant:
Get-SPOSite
So, for those private sites, the site name should be "TeamName+ChannelName"
Then to manage storage in those private sites you can use following command:
Set-SPOSite -Identity https://contoso.sharepoint.com/sites/teamName-c... -StorageQuota 1500 -StorageQuotaWarningLevel 1400
