The Addresses tab is where the Act! Addresses are mapped to Outlook/Exchange. By default, Act! only has Business and Home addresses.
However, Outlook/Exchange provides 2 additional addresses, namely, Mailing Address and Other address. Here you can map these Act! addresses
to the Outlook/Exchange equivalent. By default, there addresses are already mapped and should only be modified if you modify the address storage in Act!. Otherwise the mapping should suffice. Refer to the video tutorials for an online explanation on how to change and remap these addresses.
