Q: how can I transfer .msg files into my contacts without loosing information?

Just what do you mean?

a .msg file includes all the information in a message for Outlook. It is not just the sender's email address.

A .msg file is an email saved by Microsoft Outlook. While an email obviously contains both the sender and recipients email addresses an email is not specifically anything to do with contacts.

The equivalent file format for contacts is called Vcard and has the .vcard or .vcf file extension. It is possible for Outlook to import and export .vcard files.

While a .vcard file can contain either a single contact or multiple contacts Outlook only supports a single contact per .vcard file. (Apple's Contacts application can also import and export .vcard files and also supports multiple contacts per file.)

Apple Mail uses the .eml file format for emails. The following utility can convert between .msg and .eml formats.

See http://www.45rpmsoftware.com/mailraider.php

Once you have converted a .msg email to .eml format you can open it in Apple Mail and see it as if you had received the original email, complete with any file attachments. You can even forward it or reply to it, or file it in a folder in Apple Mail.

by definition, a .msg file is a mail message in Outlook form.

Anything can be in the message.

One can view the .msg file on a Mac using an app ike

https://sourceforge.net/projects/msgviewer/

Your screen capture lists -

• A single Microsoft Word file
• A folder probably containing addition Word files
• Four different Outlook emails in .msg format
• And a Windows Shortcut - an Alias in Mac speak which will not work on a Mac

With regards to the .msg files as previously stated these are emails saved from Outlook. A email does not necessarily contain contact information. It could be the contact is in the To and From fields again as previously stated, or it could be that a file is attached to one or more of these emails and that file attachment contains various contact details. Such a file attachment could be in the Vcard format I previously discussed.

Judging from the size of the emails I would not expect there to be a considerable number of contacts in them if at all.

I would suggest the first step is to either use the MailRaider program I linked to, or the MsgViewer program that Illaass linked to. Each will let you see the content of these emails and any files attached to them. You can then confirm they contain what you are looking for. Personally I feel MailRaider is superior and is a true Mac program whereas MsgViewer is a Java program. However MailRaider is not free although it is also not expensive.

PS. If the contacts are merely lines of text in the email then you may have to do some work yourself either copying and pasting the relevant bits one at a time in to a new contact, or if it is suitable making a CSV file (Comma Separated Values) file and importing that. If you still have access to the Contacts in Outlook you could go back to it and re-export them as Vcard files, or a CSV file.
