outlook 2010 : 0x80070057

hi all,

I've just create a new lab with windows 2003 as PDC, Exchange 2007 SP1 on Windows SErver 2008 R2 and Outlook 2010 as client on Seven Enterprise.

When outlook is trying to create automaticly the mail profile I receive an error message : unknow error occurs : 0x80070057.
This happen when outlook is looking server settings.

When I manually set the profile, I do not have the error.

Many thanks

This is a lab with only one desktop for the moment.
The computyer is in the domain

Thanks I will have a look tomorrow, especially on second quotes as I had already see the first article.

You could also check "Test email autoconfiguration" from the affected client machine.

If this fails
