Thank you Mohammad, but it doesn't work.
I try to explain better my situation:
- Office 365 Federated with our on-primise domain.
- CRM Online integrated with Office365
My user (Global Administrator in Office365) was automatically created in CRM Online during activation process and I can enter without problems.
My collegue (Global Administrator in Office365) was automatically created in CRM Online during activation process and He can enter without problems.
My Chief (Global Administrator in Office365) was automatically created in CRM Online during activation process and He can't enter and receive that error message.
All users above have a licence associated on portal.microsoftonline.com
The issue remain also with
