How can I import my OLF client address book?

Export the address book from Online Filing by saving it on your computer. Then import it into Online Filing 2.0 via the Administration, Address book tab by selecting Address book and then Import.

Note that the Street field of Online Filing consists of a single line that accepts up to 237 characters, while the Street field of Online Filing 2.0 consists of two lines that accept no more than 80 characters. If an address saved in Online Filing has more than 80 characters, you will need to rework it so that the address book can be imported without errors.
