Hi there and welcome
Exactly how did you backup your Address book before reinstalling Outlook?
I can see you are a first time user to the site. What we do here is either a question and answer type of conversation or remote support where I would actually connect to the computer and have a look and attempt to fix the problem for you.
Remote support can save a lot of time if you are not comfortable performing repairs yourself. Sometimes even with instructions you can make a mistake and make things worse.
I will send an offer through for remote support and should you accept I will connect and see what is going on and fix the issue. Otherwise we can continue to talk like this but I will need to ask a number of other questions and try and walk you through some steps.
Both options are 100% guaranteed by the way. Remote is just quicker and avoids the risk of you making a mistake and doing something wrong.
If you want remote click get extra help. If not simply reply to me.
Yes, it is an additional cost as it is an additional service, but it is optional else we continue here via messaging.
ok, but you backed it up into a PST file?
ok, click then on File, Choose Import from another program or file, and then click Next.
Choose Outlook Data File (.pst) and click Next.
Browse to your PST file and select it, then select to import contacts.
Let it complete and the contacts will then be added from the file to your address book
Let me know the results please.
It seems your selecting the wrong PST file, navigate to your external hard disk and select it from there please.
Ill connect to your computer at no extra charge and check the issue as it is very strange.
