No Exchange IMAP email inside LAN
Posted on 2010-08-26
Experts, I have a situation where a client is running Windows server 2003 and exchange 2003 and the problem is If I'm inside the LAN, using a laptop, I cannot access the users exchange email by accessing via IMAP. However, If I go outside the LAN, like from someone's home, using the same set up they can access their exchange mail account via IMAP.
All the clients desktop are using Outlook or Entourage with an exchange server setup and sending/receiving email with no problem.
