Hello all, customers usually add partners company accounts in their Azure active directory tenant as a guests but this do not let guest users to use their Office365 licensing features. This means that when a partner account is addedd to D365FO customer environment, it cannot send email through D365FO platform because Send As and Send of Behalf Of features cannot be configured between tenants for sending the e-mails. We would like ask to implement this change so Office365 licensed accounts can use send email features in other tenants.

Declining this suggestion as the Exchange REST API does not currently support this. 



The workaround is to use Aure SendGrid SMTP
