Google provides instructions on migrating Address/Contacts lists into Google Apps. See details at:

http://mail.google.com/support/bin/answer.py?answer=14024&hl=en

From a variety of mail clients, you can export your Contacts using the instructions provided on that Google page. For mail clients that are not listed on that page, you will just need to make sure to export to the .csv (comma separated) format. If the results of that export don’t seem to import well into Google, or if .csv is not an export option, you can create your own .csv using Excel and the instructions that Google provides at http://mail.google.com/support/bin/answer.py?answer=12119.

Provided below are some examples that are typical of the steps you will need to take in order to move your Address/Contacts lists into BU Google Mail.

From Thunderbird:

  1. Within Thunderbird to go (Tools->)Address Book->Tools->Export
  2. Give the File name (e.g. “addresses”) and save it to the Desktop (or similar, so you will know where it is). Also be sure to Save as type and select Comma Separated.
  3. Begin with step 2 at http://mail.google.com/support/bin/answer.py?answer=14024&hl=en in order to import the .csv file you created into Google Apps.
  4. The import of Thunderbird’s Address Book should go well. However, if the results are not what you hoped they would be, you can open “addresses.csv” in Excel and modify it so that it follows the guidelines provided by Google at http://mail.google.com/support/bin/answer.py?answer=12119.

From Horde:

  1. Go to your Contacts list within Horde and choose Select All by clicking in the top box to the left. (Of course, you can also make individual selections if you don’t want to export every address.)
  2. Click Export and choose Comma Separated Values. Then click on the Export button.
  3. Look for the resulting file which, if it’s not on your Desktop, is probably in a Downloads folder. It will have the name contacts.csv.
  4. Begin with step 2 at http://mail.google.com/support/bin/answer.py?answer=14024&hl=en in order to import the .csv file you created into Google Apps.
  5. The import of Horde’s Addresses Book should go well. However, if the results are not what you hoped they would be, you can open “contacts.csv” in Excel and modify it so that it follows the guidelines provided by Google at http://mail.google.com/support/bin/answer.py?answer=12119.
