I have exported all the data (emails, calendar, contacts etc.) from one Outlook PST file into a new PST file, and am now using this new file instead.
Everything is working well, except now my auto-complete is blank. When I start typing an email address, no suggestions are offered.
I didn't delete or rename an NK2 file, so I'm not sure why my auto-complete entries would disappear.
Can anyone explain what happened?
