Our environment is made up of Exchange 2007, Active Directory is a Windows 2003 Domain, (2 DC's) and we are running BESX 5.0.3, with over 20 active users. I have had no problems provisioning new BESX users. However; I have a problem with 1 user. It seems to stem back to the GAL. I cannot add this person via e-mail and if i browse to her name, it brings in an old e-mail address which has not been on the Exchange server in a few years as it was incorrect. So, in trying to determine what is going on here, also noticed that if I use a SmartPhone (Windows 7 - ActiveSync) or a Blackberry (One of the existing), when I do a look up and check her e-mail address, it is the old address. THis is most likely why I can't provision her in BESX. I can access this user via e-mail internally and externally to her regular address and it's fine.
