From SakeMail to Squirrelmail

This process needs to be done on the server side, so just send an email request to addressbook@artsci.wustl.edu. Be sure to include your full name and your ArtSci account login (please do not send passwords).

Your address book will be copied into Squirrelmail and will remain in Sake Mail as well. Remember that the two address books are separate, so adding or editing an address to one will not add/change in the other.

From Squirrelmail to Horde Mail

Saving the Addresses

1. Log into Squirelmail
2. Open the Address book by clicking Addresses from the top menu
3. Click the button Export to CSV File at the bottom of the list. Save the file to your desktop.
4. Sign out of Squirrelmail

Move them into Horde

1. Log into Horde Mail
2. Expand Organizing from the left menu and click on Address Book
   
3. Click Import/ Export from the top menu
4. For the format of the source file, select Comma separated values
   
5. The next field asks you to select the file to import. Browse to the file you saved in step one. It should be called (your user name)-addressbook.csv.
6. Click Next to import the file.
7. The next screen asks you about the data you are importing. Your answers should match the illustration below. Be sure to uncheck the box next to this question: "Does the first row contain the field names?" And click Next
   
8. The next screen will require you to match sample content from the old address book to the available fields in the new one. Highlight each pair and click Add Pair to move them into the matching fields category. It’s OK if you have data left over that does not fit into the remaining Available fields, that data will just not be imported into the Horde Mail address book. Click Next when you are finished matching pairs.
9. You should now be able to see all of the imported data when you browse your address book.
