Hi Everyone, I have a question about a problem with some Apple's users. Sometime the receive messages that keep stuck on the mailbox and there is no way to do any thing. They are not authenticated with the domain, and they are using as client the regular mail from Apple. The message gives us a hard time because it is not able to send or receive message and on the event viewer, I got a lot of POP3 error because of it. I used the outlook express in a PC machine to receive the messages, but has one message that looks like isn't going anywhere, even when I tried to use the OWA. Message number 1 could not be retrieved. Account.'10.10.10.54', Server: '10.10.10.54' Protocol: POP3, Server Response: '-ERR Unrecognized internal error: 0x800cce05', Port: 110, Secure (SSL): No, Server Error: 0X800CCC90, Error Number: 0x800420CD Please, any suggestions or tools or any clue will be more than welcome, because I have been dealing with this for a long time and I tried everything to fix it.
