LIST failed: Invalid UIDL response: 827

I am suddenly getting the following message when trying to connect (pop3) to a RoadRunner account:

Failure communicating with remote server. Please try again later.

Debug message: LIST failed: Invalid UIDL response: 827

Exception:

Howw about an idea of which version of Zimbra Desktop you're using?

[candem]

Zimbra Desktop 1.0.4 Build 1833

Win 7 Home Premium 64-bit

Thanks

Have you tried the new Zimbra Desktop 2 which was released a short while ago? You should try that version, make sure you read the Installation & Setup, Release Notes and FAQ before you install.

Sorry, you may find that this doesn't work in ZD either. Is your ZD1 a new install or are you connecting to the POP3 server for the first time? You may actually be hitting this bug: Bug 30643 – Optional Support to disable UIDL-Requirement for POP3 Servers
