I am trying out the "Zimbra Desktop 2.0.1" and get an error when I try to attach to my Zimbra account. But only for *one* account.

"account.INVALID_ATTR_VALUE: must include domain"

When I try other accounts at the same server all works as expected.

Server: ZCS-network, 6.0.10

example account:
account: name.name@domain.com
mail: name.name@domain.com
password: **********
Mail server: mail.domain.com
SSL / 443
