Enable "Open in Client" Feature in a Tenant's Site Collections

[Thanuja Seneviratne]

Hi,

I would like to know how to enable the "open in the client" feature for all the site collections in an office 365 tenant. I mean instead go to each site's site collection feature to enable it, any client-side script-like solution for this? or PowerShell the better solution?

Thanks

Sure, this is something you should easily achieve with PowerShell using CSOM API

Thanks we figured out PS solution for enabling this feature for all the existing sites. But let's say if we need to automatically enable it when a new site collection created, a possible solution?

Appreciate a code sample/positive feedback.
