I haven't used this in quite awhile, but I tried to walk a customer through setting up the account. As well as setting up an account locally on my PC.  The account is created fine, and I see it under Connectivity on both accounts, but mail is never downloaded, calendar and contacts don't populate either.

Only thing I see in the logs:
