Google is offering firms a managed e-mail archiving service that will cover messages for up to ten years.
Google said the offer would help firms cope with data compliance demands and speed e-mail access requirements.
As part of the move, Google has simplified the pricing of its hosted e-mail security and archiving package Google Message Discovery.
For a flat fee of around £26 per user per year, firms can now add hosted archiving with the ability to retain messages for up to 10 years, along with spam and virus filtering.
The service is powered by the technology Google acquired when it bought Postini last year.
"When the total cost of an on-premise security and archiving system is taken into account, keeping e-mail over the course of seven years can cost more than £120 per user per year. Taking advantage of Google's economies of scale, you can achieve the same objectives for only about £26 per user per year," said Google in an enterprise blog.
