Hi, I have the following problem I can't seem to solve: Since a week or two one user (let's call em user A) cannot send (external) internet e-mail anymore (SMTP), they leave the outbox, but never arrive. Other users seemingly do not suffer this problem. Receiving (both external and internal) is never a problem. Our configuration is as follows: the server is Exchange 2003 and the clients are set up to make use of the exchange server, along with internet email, using Outlook 2000 clients. All of the other clients are set up so that they can view the calander of A, which still works for everyone. There is also a second user (B), wich is actually a login for a laptop used by A (so they use the same mailbox and everything, but the laptop has a different windows login and is configured for offline use as well). I have tried narrowing down the problem. The internet e-mail account of A is not the problem, as B (on the laptop) can still send external emails and I'm able to send mails through the webmail front of my ISP. The PC is also not the problem I believe. I have created an account A on the laptop and used it to test whether the Outlook 2000 intall on the desktop PC had gone bad or something, but sure enough, when using account A on the laptop the user is also unable to send internet email. All of this leads me to believe that this issue is specific to the user account (A). So I checked the server. I turns out all the mails sent by A end up queued. Incidently, the queue also contained some other emails by other users, but these were sparse only a fraction of the total queue. (Nonetheless, I find it odd that the had problems as well, but that's not the pressing issue at the moment.) I turned on message tracking to check what was happening. It turns out only messages sent by user A show up in the logs. I don't know if this is normal or not, never having used message tracking before, but I think this may be where the problem lies. It's been years since I set up the server and it's been running fine until now with these problems. I had always thought our Exchange server did not handle external e-mail at all, since I never set up the SMTP server on the Exchange server or anything and just configured the clients with "Internet e-mail" and "Microsoft Exchange Server" in Outlook 2000. It was my understanding that all internet e-mail was handled solely by Outlook (the delivery order is set up as: "Internet e-mail, transport microsoft exchange, transport microsoft exchange remote", in descending order). So if that is the case, something must have happened that caused this user A to be treated or behave differently. I've been searching for a solution for a while now, but I'm still not any closer to a solution, hence this message. I'd just chuck the user/mailbox account and recreate it, but it is the main user that all other users depend on (for the calander at least), also the mailbox is getting to be quite large at least compared to other users (bout 800 megs now, maybe that's the cause?). Anyway, any help is greatly appreciated. If more info or details are needed, I will be happy to provide them.
