I moved Outlook to a new system and imported the PST file, emails are fine, but no contacts were imported. I have several archive PST files, I opened those (didn't import) and I contacts weren't there.
In contacts, in the left column, it shows the the particular PST file is open and gives you the option to view them but, again, none are there.
I've never had this issue in the past. Are contacts saved in all PST files? eg: achive files.
