Answer 1

Suggest you try the following way:

URL:

Post https://login.microsoftonline.com/<tenant_id>/oauth2/v2.0/token

Content-Type:

application/x-www-form-urlencoded

Request body:

client_id=<client_id>&
scope=https://graph.microsot.com/Mail.Read openid User.Read&
grant_type=password&
username=<email_id>&
client_secret=<client_secret>&
password=<password>

And the response:

Answer 2

For me the below worked out in Postman.

URL(POST) :

https://login.microsoftonline.com/<tenant_id>/oauth2/v2.0/token

Header:

Content-Type 
application/x-www-form-urlencoded

Request Body(text):

client_id=<client_id>&
scope=https://graph.microsoft.com/.default&
grant_type=client_credentials&
client_secret=<client_secret>
