Answer 1

In most cases this error means that the connection was interrupted. It was lost, the server disconnected or your antivirus/firewall cut the connection.

In technical terms, it means exactly what the exception’s message says: component tried to read a line (ending with CRLF), the line was expected in accordance to the protocol in use, but it has not been received during the specified period.

On extremely slow networks you may increase timeout values: ReceiveTimeout and SendTimeout.
If increasing timeout values doesn’t help, it means that the connection was dropped by the remote server or some intermediary router – you’ll need to connect again.

If you are trying to download MessageInfos for particularity large number of uids, consider breaking it in to smaller batches - maybe that is a problem for our server.
