I have a weird one that doesn't make any sense to me- Exchange 2007 | Windows 2008 Functional Mode |One GAL, One org Created several thousands contacts w/ powershell. Includes fields, like name, title, department, phone, etc. I can look these people up in the GAL and send email to them. However if I receive email from them, open it, highlight their name and choose one of the following- Contact Card, Lookup Contact Card, or Outlook properties It acts as if it is a foreign address, not in my GAL. I imagine this works on a reverse lookup of the primary SMTP address against the GAL. This value matches, but yet all I see are the display name, and email address that were in the header of the original email. Any thoughts on what I am missing? Thanks! Jon
