The release of Microsoft Exchange 2010 substantially increased the maximum database size that can be handled by its core messaging engine to 16TB (Terabyte). This is 10 times more than the 200GB (Gigabyte) supported in Exchange 2007, and must appeal to companies looking to support more users or larger mailbox quotas. Of course, the maximum supported size does not necessarily conform to best practice sizes recommended by Microsoft, for which the Microsoft Exchange team has released a detailed spreadsheet documenting the various scalability limits here. (You will need Excel 2007 and later to open it)
Regardless of the Exchange Server version in use, enterprises have a number of techniques to support the needs of their organization. What I want to talk about today however, are some considerations that email administrators and IT managers should evaluate prior to upping the limits on their corporate inbox.
Computing the storage cost
The most obvious argument against large mailboxes would of course be the dollar cost that acquiring additional storage space will incur. While hard disk storage has plunged in recent years, assigning 10GB inboxes instead of 2GB or even 5GB ones does add up to a hefty amount. In addition, there is also a need to factor in the cost of data mirroring technologies too, which can result in a doubling of storage space if RAID1 is used, for example. Factor in the corresponding increase necessary for offline or archival storage, and the storage requirements goes up higher still. Clearly, performing a linear computation multiplying users with their mail quota is not an accurate way to determine the true cost of any increase in quota
