I've got one that's kinda been puzzling me. I've got a user that very occasionally finds that his desktop email client (Mac's default email program) will not list an email message while both his phone and the msu webmail client will show it. Eventually, anywhere from a few to 12 hours later, the message will show up on the desktop. Both the phone and desktop client are using imap, and the settings look fine on the client. It doesn't really feel to me like it's an issue on the MSU end, since multiple other imap clients (web and phone) are seeing the message. And as far as he's noticed, it's always been the mac email program that's missing the message. I know MSU's been updating their pop and imap servers, but I don't *think* it's related, since a previous email that he had this problem with happened about a month ago (And that's part of our problem trying to track this down, it's very infrequent, and of course, never happens at a time when I can look at the systems while they're in the state where it's missing the email). He does have a fair amount of email in his inbox on the server, but I've never seen that cause this issue elsewhere. Anyone ever run into something like this? I haven't tried contacting the help desk because like I said, it doesn't really feel to me like it's an issue on the MSU side, and I also haven't been able to catch it during the time when it's happening (I figure maybe at least if I can get it while it's in that state, maybe there's something MSU would be able to find on their end, but when things are working, not much is going to be obvious).
