As part of the “small” announcements made by Microsoft at Ignite, we have an increase in the number of site collections that can be created in a SharePoint Online (SPO) tenant: 2.000.000. As I say many times to customer, SPO is a highly scalable service and this new limit reinforces that message bearing in mind previous limits where 500.000 site collections per tenant and then 1.000.0000.
