1) First, find the Account Information category.
2) Go to List Accounts.
3) Find the row containing the account whose owner you wish to change, then scroll right.
4) Hover over the row to activate the edit links.
5) Then, click the edit icon under the account's current owner.
6) Select a new owner from the list.
7) Then, click OK.
That's it! The account's owner has now been changed.
8) You can also change an account's owner by going to the Reseller Center, under Resellers.
Here it is.
You can change the ownership of a single account with this link, above. Or, change the ownership of multiple accounts with the link below.
When changing ownership of multiple accounts, be sure to select the reseller from the list which you want to be the new owner of the accounts.
