Hello Experts, I have user who had exported their contacts to a PST file. Then they were changing things and really messed up all of their contacts. They want to delete their contacts and then import all the contacts from the PST file, which is supposedly good. My question is: What is the safest way to remove all the current contact information and import the PST "backup"?
I want to avoid making this worse!
