Gmail Apps Storage Increase

The Google Apps Email Storage!

Gmail offers 10 GB of free storage for your messages and attachments, and we're adding more space as fast as we can. Your storage use is based on the size of all of the messages and attachments in your mail, including those in Spam and Trash. You can check how much space you're using and your storage limit at the bottom of any Gmail page.
If you approach your storage limit, the quota indicator will change from green to red. If you go over your limit, incoming messages to your account will be returned to the sender.
If you've hit your limit and need to clear space, you'll need to move messages to Trash and permanently delete them from there.
To find messages that are larger in size due to attachments, try using advanced search operators such as has:attachment or filename:mov.
To move a message to Trash: To permanently delete a specific message: To permanently delete all of the messages in your Trash at once: Messages left in Trash for 30 days will be permanently deleted automatically. Messages that are permanently deleted, manually or automatically, cannot be recovered.
