Now that we've seen the theory, let's go
in the lab environment and check out how
we can configure external sharing at the
site collection level. We are now in the
lab environment, and let me open up the
admin center. Go to active sites, and for
this demo, we're going to play with the
Drones at Globomantics site. In order to
change external sharing settings, we have
to select it, and then click on Sharing.
However, the only feature we can actually
configure by using the user interface is
what is the most permissive level that
users can share with; between anyone, new
and existing guest, existing guest only,
and only people in your organization. None
of the other settings are available via
the user interface so what do we do? We
use PowerShell. So let me go in PowerShell
over here. In order to change the
properties at the site level, we use the
Set-SPOSite PowerShell cmdlet, specify the
identity of the site that we want to
modify, and then give it all of the
different parameters that we want to
modify. In this example, I'll set that
first of all the default link permission
is edit, default sharing link type is
internal, sharing capability will be
anonymous, most permissive sharing
capability will be anyone with external
user and guest sharing, and show people
picker suggestions for guest is false. We
can also modify other things in this other
example. I will set the domain allow or
block list. So in order to do that, we
first need to run the Set-SPOSite again
and specify the site that we want to
change the settings on, and then I will
set the sharing domain restriction mode to
allow list, and sharing allowed domain
list only globomantics.org. So this is
really the setting for this specific site
collection. Remember that settings must be
more restrictive than the tenant level
ones, so globomantics.org. So if at the
tenant level you have domain allow list
enabled and globomantics.org is not in
that list, it will not work. However, if
you don't have that allow or block list at
the tenant level, you can set whatever
domain you want at the site level. Now
let's go into, let's first of all refresh
the admin center, see that the change has
been done. Then we will go to Drones at
globomantics.org, go into Sharing, and
we'll see that site content got updated
what can be shared with anyone. However,
all of the other settings, you will only
see them in PowerShell. This is it for
this demo on how to configure external
sharing at the site collection level. Now
let's go back in the slides and take a
look at some scenarios in how we could
configure external sharing for our organization.
