The last two days, around 5:30am, a lot of delayed emails are being sent to our users. Some of them are a day or two old but some are up to a week old. When I look in the spam filter, I see them going through at the correct time so I think it's something with Exchange. Is there a log or something I can look at for a specific email that was delayed to see why? I restarted the Transport service yesterday but we still received a bunch of delayed emails this morning. We are on Exchange 2010.
