Google has announced a unified storage plan in which storage is allocated in one bundle to their Google Gmail, Drive and Google+ services.  We expect to see this roll out to Enterprise customers after May 21.

"As a result of today’s storage change, Gmail inboxes for Google Apps customers are no longer limited to 25 GB - any additional storage you purchase can be shared and used by Gmail. Or alternatively, if you’re only using a few gigabytes of email storage, but have a lot of large documents and files stored in Google Drive, you can now use your storage primarily for Drive."

This means everyone at the lab will have 30GB to use however they wish. Those of you who are close to the current maximum of 25GB in Gmail will now have some additional space (assuming you do not use it in Drive).  

We have around 100 customers at the lab who will benefit from this from a GMail perspective. Many more will benefit from having more Drive Space (many Gmail users are never close to 25GB).  In addition, additional storage can be purchased which effectively  eliminates any  need to periodically delete messages when the max limit has been reached.
