Energizing Exchange: Page 2 of 7

Hudson says the upgrade went fine, and Exchange is one less thing he and his small IT staff have to worry about.

Don't get too attached
MessageOne will add a service targeted specifically at Exchange attachments to its Email Management Services (EMS) offering next month. EMS uses single-instance storage, saving one attachment in the customer's Exchange store and sending other copies of that attachment to the MessageOne archive. EMS says that could slash Exchange data by up to 80 percent.

But Erica Driver, principal analyst at Forrester Research, warns that users should do some serious thinking before they go down the outsourcing route for archiving. "The decision point should be how quickly do I need to get the archive up and running, and do we have the internal IT resources," she explains.

In many cases, according to Driver, desperation will force firms into the arms of an outsourcer. "If you're a financial services company, and NASD comes to you and says that you're not archiving your emails and IMs, you're going to do it immediately through a hosted partner," she adds.

Set limits

Enforce strict quotas, and don't let your users talk you out of them - unless it's your boss or somebody with an exceptional reason for needing more capacity.
