KB Issue

When you create a new email account under your Google Apps account for your domain, the user may encounter issues with login to the account while using 3rd party email programs such as outlook express.

Issue Details

When an email account is created inside of Google Apps, and the user does not log in to the account, but there is activity on the account that sends emails out, this can cause the account to become suspended.

The cause of this is for security on Google's side.
If the user does not log in to the web interface but has many outgoing emails, it may look like potential abuse/spam.
So, having the user log in to the web interface account lets the system know it is a real account, not created for abuse.

Recreate Issue

Create a new account in your domains Google Apps account.
Do not login with the new account.
Set the account up to send emails only, not to receive them.
After this is done a few times in a high volume, the account with be put under suspension.

Resolve Issue

Create a new account in your domains Google Apps account.
Log in to the account through the Google Apps page or Gmail.com.
This login will reactivate the account and remove the Suspended mark.
