When Schemus established a remote session to https://ps.outlook.com/powershell, the URL automatically redirects it to servers hosting your Office 365 resources, once the remote session is created, it will then import that session’s commands (get-user, get-contact, get-group, get-recipient) into your local Windows PowerShell session and it will begin to use these cmdlets to retrieve attributes from the Office 365 services.
The default value for Exchange Online in the Access URL should not need to be changed in the schemus configuration. If you change this line by accident, click on the Reset Defaults buttons to restore the original value. This can be changed under Edit > Settings > Exchange Online > Reset Defaults. The controls allow you to set the default details for connecting to the Exchange Online server.
