When I log in to my Google Apps email I get a message that says my account has been disabled!
The disabling are done so automatically by Google when their systems detect irregular activity on the account, usually excessive emails which they determine are spam in nature.
If find your account disabled please reset the following:
NetID password: https://go.illinois.edu/password
IMAP password: https://partnercomputing.illinois.edu/password
Once you have reset those two, contact the Help Desk. They will make a ticket to have your account enabled again.
