Entourage X - Could not retrieve mail from the account

[QM]

I just installed Entourage X.
I can get and send mail using MAC OS X "Mail".
Using the new Entourage I get:

Could not retrieve mail from the account ...
An error has occurred (-1).

I checked carefully all the settings including the incoming port (110) which
works for Mac Mail too.
When I use Entourage 2001 I do receive mails.
I am using DHCP (if it makes any difference.

Any help out there ?

Thanks
Joe
