Changing the Skype account that your Skype minutes are linked to
To switch your minutes to a different Skype account, take the following steps:
Go to www.office.com/deactivateskype and deactivate Skype.
Then, follow the same steps you took to activate your Skype minutes originally:
Go to www.office.com/myaccount and sign in.
Click the Activate your Skype minutes button.
Follow the instructions on that page. (Sign in to the Skype account you want to link your Skype minutes to.)
Important: You can change the linked Skype account only once, so make sure you pick the right account when you activate your Skype minutes on a different account.
