Trying to get a fresh isntall of exchange deployed but I'm having some issues. I've managed to get it up and running and it can send and recieve emails with no issues. The problem I'm facing is that on several users (not all) i get an error message when trying to access the properies of the recipient in EMC. In Active Directory I can access all the properties with no problems. Following the text int he error message:
"the properties on this object have invalid data. if you click OK, default values will be used instead and will be saved if you do not change them before hitting apply or ok on the property page. if you click cancel, the object will be displayed read-only and computed values will be retained"
