yesterday i used a tool for migrating my data from thunderbird to ms outlook. i used this utility https://www.spikevare.com/thunderbird/, but the problem is when i migrate data from Thunderbird to outlook address book did not migrated because this software converts mbox to pst. i exported my address book in csv file format but there is no option available in outlook to import csv file. can anyone help me to import my exported address book from thunderbird to outlook 2013. please help me this is very urgent for me because i am not able to access my address book and i have more than 2000 contacts. every time i need to check from my excel file and copy paste each contact that is time consuming
