Office 2011 for Mac: Import Contacts from Text Files to Outlook
To import contacts into Outlook 2011 for Mac, you sometimes need to make a .csv file of your contacts in a different e-mail program. Outlook 2011 for Mac also supports delimited text file formats such as tab (.txt), comma (.csv), and MBOX file formats, which you can use if your old e-mail program is capable of saving in these formats.
Importing Contacts is straightforward using a short series of dialogs:
In Outlook, choose File→Import from the menu bar.
Select Contacts or Messages from a Text File and then click the right-arrow button at the lower-right corner of the dialog.
Depending on the file type you need to import, choose either
Import Contacts from a Tab- or Comma-Delimited Text File.
Import Messages from an MBOX-Format Text File.
Click the right-arrow in the lower-right corner of the dialog to display the Import Text File dialog file browser.
Click the Import button.
Outlook displays the Import Contacts dialog.
Choose the field names from your old e-mail programs to equate them with Outlook's fields using the Import Contacts dialog. This maps the old e-mail program's field names to Outlook's field names.
Click Import and then, in the next dialog, click Finish.
Your contacts from the old e-mail program are now in your Outlook Contacts list.
