Exchange Online authorize problem

Hello, my problem is i cannot get to authorize my Exchange online server for sending emails from Sugar.
Using Sugar Enterprise 13.0.3 , on premises.

The Microsoft connector is set up and enabled
I go to "System Email settings" > Exchange Online > i fill in the required fields , and i click Authorize button
Microsoft SSO pops up
I select the account i am currently logged on to Sugar, which is a 365 account with global admin role
I fill in the password
i Approve from my authenticator app
(the authentication on microsoft is successful)

The Sugar popup window ends like this:

I close the window, and the status of the Exchange Online is still Not Authorized 

Any idea?
