Gmail – Is Gmail Priority Inbox only for Google Apps accounts

Are you asking if the account will be deleted? If so, the answer is no according to Google.

Google will not delete inactive email accounts on your domain. Instead, as an administrator, you can create and delete email accounts on your domain when necessary.

EDIT: Once the account is setup, it doesn't seem like it but I'm not certain. There's no mention of inactivity other than verifying the setup here: http://www.google.com/support/a/bin/answer.py?answer=33419

Your account has been deactivated or deleted. For example, Google deactivates your account if you do not complete the steps required to verify ownership of the domain within 14 days (7 days for Standard Edition). It is also possible for an administrator at your domain to manually delete the account. In either case, you will need to go to http://www.google.com/a to reregister your domain. You will have to wait five days from the time the account was deleted before reregistering. Any data in the deleted account will be lost.

Google generally does phased roll-outs, so you generally may not see everything when it is first released. Roll-outs to GAFYD are generally later also.

However, Google differentiates between full release publishes and beta pre-release publishes. By default, Google won't push pre-release features on you. This is something the administrator for your domain will need to do.

Pre-release Features

By selecting this option, your users will be able to see and use new services and features at the same time as consumer users of Google's applications. We sometimes delay the launch of features like group chat and colored labels to Google Apps accounts because we want to ensure that all the features we bring to the Google Apps suite are useful and stable before providing them to our business, education and organizational users.

To opt-in for pre-release features:

1. Log in to the Google Apps administrator control panel. The URL is https://www.google.com/a/cpanel/primary-domain-name, where primary-domain-name is the domain name you used to sign up for Google Apps.

2. Click Domain settings.

3. Under the General tab, and in the New services and Pre-release Features section, check the box next to Enable pre-release features.

4. Click Save changes.

Your users will have access to a new feature at the time of the initial launch, rather than when it rolls out to all Google Apps accounts. These features should be considered in testing for Google Apps, and we are unfortunately unable to offer support for these specific features.

Please note that you can edit your selection in the future. It may take up to a day for the change to take effect in your users' accounts.
