Whether it is to meet operational needs, litigation readiness and eDiscovery, compliance, end-user liability, costs and other issues that come with corporate email communication, an email retention policy is always a great asset to help manage, store and archive corporate email messages. Even more so when research estimates that up to 75% of email content is considered critical to the successful operation of an organization (Osterman).

The answer for most organizations may clearly be in the affirmative. Companies which fall under Sarbanes-Oxley, SEC 17a-3/4, NASD 3010 or HIPAA regulations will need to have an email retention policy. Organizations seeking to pass a SAS 70 audit will want to have a policy even if no law or regulation requires it. Companies involved in litigation may find themselves required by court order to retain emails if they do not already have a policy in place. If a particular business does not fall under any of these categories, it may want to implement an email retention policy just the same to position itself ahead of any future need, and also to take advantage of the operational benefits email retention offers.
This is another question that does not have a simple, one-size-fits-all answer as it can vary from industry to industry, and smaller companies may have different requirements from larger ones. If the company has a Documents Retention Specialist, it should consult him/her first to check what may be required and what policies are already in place regarding the retention of paper records. The company's corporate counsel is another resource, and should have specifics on any laws or contractual obligations that could affect the email retention policy. The important things to include are clear and easy to understand requirements that are well documented, explained to all users, and that are enforced consistently across the organization. It should also address when email should be deleted, and provide for a way to ensure that this occurs when it should. Of course, the business stakeholders should be included to ensure that the policy supports, rather than hinders, the business.
What about legal holds?
It is likely that an organization will be involved in litigation at some point during its history. Legal holds can come into play and could supersede any email retention policy that addresses destruction of data. Ensure that the technical systems in use have a way to store all email for any or all users covered by any court order or discovery request, and that it can prevent users from inadvertently deleting emails.
There are several key points that will mean the answer is "now", these include:
Among the benefits to having an email retention policies are:
