I have clients at a remote site that are using RPC over HTTPS to access their e-mail using Outlook 2003. They can access everything just fine, but they are having a few annoying issues, such as their rules running minutes after e-mail is delivered to their mailbox and when they send mail it looks like the message is stuck in the outbox, but it is not, the mail was actually sent, it is just that the outbox did not refresh. What leads me to believe that it has to do with RPC over HTTPS is because only the users using it are having these weird problems. Any ideas?
