Hello ,

I have an Exchange 2007 Installation in a multinode enviroment. Its about 3000 users. Suddenly today a user cannot connect to his mailbox. He can connect without problems from OWA but with mapi in outlook 2010 it keeps asking for Password.

I try to setup his account in a new computer and outlook profile and when setup finishes and outlook starts for first time i take the error " Cannot open your default email folders . You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your outlook data file (.ost) " 

Any ideas please? I don't know what to do .

Thanks
