When a create a group a put the members of it inside the group. If i look at site permissions (in members group) there will be only one "user" (Ad group) with the same name of the office 365 group that generated the site.
Then, I am using microsoft flow to send a email to the email of the office 365 group created. To do this I make a query to Sharepoint API like this:
_api/web/SiteGroups/GetById(5)/Users. However, when a get the only one member returned by this request, which is the "user" that has the same name of the office 365 group, the email field is empty.
Someone knows why this is happening? I need the group email to send a message, but the email field return by
_api/web/SiteGroups/GetById(5)/Users is empty, when it should be filled.
