Hi Churchill,
Thanks for your reply.
I followed your suggestions and added them to the trusted sites, but I am still facing the problem.
1) I browse to the crm.dynamics.com and select the right "sign in" portal, no microsoft online service(Office 365)
2) Then I meet the following problem
I have posted the questions in this forum for several days, but no Microsoft's guys aswer my questions.
Don't understand why the Microsoft's Office 365 team, Microsoft Office team can reply to the questions in time, but the microsoft Dynamics team seems don't care about the questions in this forum.
Our company has spent a lot money to buy Dynamics, SharePoint,SQL Server, Windows Server, and we has Dynamics Partner Source and Dynamics Customer Source, if no MSFT's guy answer the questions, i will try to call Microsoft's service line and complain this problem.
