Hello,
Outlook and Scalix webmail both allow importing contacts from csv or ldif file.
To convert the text file into a .csf file,You can use the 'Import Text File' option in Excel at
Data -> Import External Data -> Import data .
It then should allow you to specify the different fields. Import it and then save it out as a .CSV file
To use webmail to import contacts, you can follow the link,
http://scalix.org/wiki/index.php?title= ... Fldif_fileTo use outlook to import contacts,
Outlook -> files -> import and export -> Import from another program or file -> Comma separated values (windows)
browse to your .csv file and complete the import/export wizard.
