Is there any way to add O365 mailbox on behalf on other user as a administrator ?
Since basic authentication deprecation in Exchange Online there is a OAuth 2.0 token-based authorization. Based on that we would like to add users mailboxes.
We can only add mailbox of the user logged in to O365 so after providing mailbox name (eg. firstname.lastname@example.org) Creatio redirects to Microsoft login page and after login replace mailbox name to current user name (eg. email@example.com).
In other words we need to login to each mailbox via Microsoft identity server to add it to Creatio.
Is there possibility for administrator to add user mailboxes to Creatio without knowing their O365 passwords?
