Import mail addresses from mail into outlook address book

We had a computer disk malfunction, and system died. All files were OK, and mails are on IMAP, so also OK.

However, address book from outlook was lost.

Does anyone know of a way to extract email addresses (not names necessarily) into the Outlook address book?

Outlook in Q is 2013.

Can you still see it in Outlook or not? If somehow that file is deleted, I doubt on anyway to recover it.

I ned a solution how to extract email addresses from the received/sent emails, not how to restore a PST / OST.

Simplest solution would be to use the Outlook export wizard to export the email addresses to a csv file from the desired folders. Be sure to select <Map Custom fields> to select the desired email address fields

Once that's done, you'll need to open the file in Excel and split the email address fields for those that contain multiple email addresses. After that you'll need to copy all the secondary email addresses to the first column so you end up with a single field to import. You will also have to check for duplicates in the column then save the finished product to a csv file

Use the Outlook import wizard to import the csv file to the <Email Addess> field in the contact folder that is designated as the default contact folder contained in the default data file for the profile.

Since this involves an IMAP account & OL'2013 and <IF> your default contact folder is contained in the IMAP folder tree (will show the added words "This Computer Only") - then I would suggest creating a new PST file in this profile and make it the default data file for the profile so that it contains the default contact/calendar folders. It's never a good idea to maintain any data in any folder marked as "This Computer Only" since if Outlook can't located the associated .ost file for the account, it will recreate it and re-sync the email folders and have empty contact/calendar folders. Equally, if an IMAP account gets deleted so does the associated ost file and all data in "This Computer Only" folders will be lost

Changing the "default data file" has no impact on what email account is set as the default.

How to Protect Outlook '2013/'2016 Imap Contact/Calendar Data

An alternative to the above is to create a free account, add it to the Outlook profile, import the contacts to the contacts folder and then set the .ost data file for the account the default data file for the profile. Tht way contact/calendar data will be accessible to any device where the account is configured. is an Exchange acct so all folders are sync'd including contact/calendar folders. There's no need to use the account for email
