If you need to update the details for your organisation's Adobe VIP account, you need to be able to login to it.
Unfortunately, we cannot change any of the registered details (such as contact person or email address) on your behalf, nor can we reset the password for your account.
Once you have signed in, follow Adobe's steps on how to change your 'contract owner' here - https://helpx.adobe.com/au/enterprise/using/change-contract-owner.html
If you can't access your account, let us know as we can add additional administrators to your account.
