I recently had to set up team ownership in Dynamics CRM for 1600 Accounts across 40+ Teams. Because of these large numbers, I decided to use the out-of-the-box Import Wizard to speed up the process.
I started with the data import template available for the Team entity and entered the information about three new Teams as shown above.
