To resolve the issue of conflicting accounts, you will need to login to Google using the username [your @gmsdk12.org username]%gmsdk12.org@gtempaccount.com and the password you had previously configured for your @gmsdk12.org Google account. For example, if your email address is chris.cooper@gmsdk12.org, you would sign into Google using the username chris.cooper%gmsdk12.org@gtempaccount.com, and the password that you had previously used when signing into Google as chris.cooper@gmsdk12.org.
